Misfire? bogging down? (vts) UPDATE more problems

  1. #1
    Right il try and explain the problem the best i can, one minute the cars working ok, was driving around then all off a sudden the car produced no more power unless i really put my foot to the floor, between 500 rpm (this was the idle btw lol) and 4000 rpm its was really struggling, bogging down as if i was running out of fuel but over 4000 rpm it was ok? idle was really bad (500rpm and sounded like misfire) left it overnight and all was good in the morning (typical saxo lol)

    Changed the plugs for good measure and had no problems until today, started doing exactly the same again, was only 2 miles from home so managed to get home, as soon as im home all is well again lol?

    I have no idea what todo next
  2. #2
    coil pack?? ht leads??
  3. #3
    possibly the coil pack starting to go. I'd see if you can borrow one to try on your car and see if that cures it. Unless you have a dodgy plug?
  4. #4
    similer thing happend to my mates 106, all he needed was new HT leads, but tbh im not sure
  5. #5
    just found out im due an mot so il get a diagnostic done first, as you say im sure its the coil pack but not going to fork out £100 odd incase its not, cheers
  6. #6
    have you sorted your problem yet mate my cars suffering the exact same symptoms apart from iv changed coilpack with no luck!
  7. #7
    me too, exact same problem! changed coil pack, plugs, lambda sensor, engine temp sensor for ecu, took off inlet manifold and throttle body and cleaned thoroughly!! still not cured , would be curios how ya sorted yours? cheers
  8. #8
    could be injectors? Possibly fuel pump etc
  9. #9
    mine did this but without miss fire.
    check spark plugs, coil back.

    Mine idles a bit rough, but i think its map sensor.

    Check your inlet mani nuts as mine were loose as fuck.
  10. #10
    Iv changed near enough everything now with still no change

    MAP Sensor
    Idle Control Valve
    Coolant Temp Sensor
    Coil Pack
    Spark Plugs
    Cleaned all the throttle body out
    Had compression tested and that come back fine

    Its really weird its jus got no power what so ever until about 3500-4000rpm

    you dont get ht leads on a vts.


    mass air flow sensor mate.
  12. #12
    mine does exactly the same
    love to no what the problem is!
  13. #13
    did it again the other night, still no idea what it is, its annoying as hell
  14. #14
    I have this problem but mine only between 1200 rpm and 2000rpm.
  15. #15
    any one try changing the relay box under the ecu? ive it narrowed down to that or injectors, will know more tommorrow.
  16. #16
    Crikey god damn Vts. Aaa lovely mine has just started doing it too except its all the way through the revs. Doesnt get better at all and it is a missfire. Im guessing i will have to change the coil pack tomorrow and see if that does it. I have a couple lying round for a rainy day
  17. #17
    i had the same problem, turned out to be the idle control valve and the air filter was sucking too much air in around the edges. and if i am low on fuel it sometimes does what youve descirbed, but i think my fuel gauge isnt entirely accurate.
  18. #18
    Did it again today, had to drive it 40 miles at over 4000 rpm, flamming car, anthonyk if you find the problem let us know mate
  19. #19
    I had a similar problem to this when my Lambda Sensor went on the blick.

    hmmmm somthing else i need to look at lol, also tonight it was very wet and as soon as i drove over a thin puddle at 60mph it did it, so maybe water/electrical related.
  21. #21
    Have you had it on a diagnostic machine? Any engine management lights on?

    had a diagnostic for the abs sensor as a favour from a mate so dont thing he checked anything else, no management light at all, another full diagnostic is on the cards first i think.
  23. #23
    Yeah best to get it looked at mate. Try and find a decent garage round your way rather than go to Citroen. Might well be something which isn't too difficult to correct.
  24. #24
    UPDATE - little update, car was reving itself earlier once hot, from idle (880 rpm) too 1200, up and down pretty quickly, dont know if this is a related problem?

    AND also when startin the car cold, id turn the key, the car would goto idle then cut out, so had to give it a little rev to keep it going.
  25. #25
    I've got exactly the same problem as you by the sounds of it, I'm going to the scrapyard now to see if they've got a lambda sensor. I'll let you know how it goes
  26. #26
    Right I've fitted the new lambda sensor now, been on a quick 5minute drive and the car seemed ok, I'll be driving for an hour later on so I'll see how it goes then.

    In the last 6 months I've changed:

    Coilpack
    Fuel pump
    Fuel filter
    Spark plugs
    Engine coolant sensor
    ICV
    Headgasket
    Battery
    Lambda sensor (today)

    I think that's everything that I've done, so you can probably rule all of them out lol

    so everything in that list didnt cure it, apart from lambda whish you will find out later.
  28. #28
    i have just got a vts and ot similar symptoms, have a spare coilpack from my old 106gti to maybe try...keep us updated guys, is it me or does the car seem to be fine for a while then decide it wants to rev a bit or bog down or cut out? and it does it just as you think its fine
  29. #29
    yeah mine can go a full week being fine then just do it, then be fine again
  30. #30
    my v5ts is doing this. when i run in the morning it rund fine.when it gets a little warmer.start running rough, not running smooth ,somtimes it coughs alot then it cuts out. when i drive feels like im tapping the brakes somtimes. even at 70mph lol. aint sorted anything out yet.

    from that list 2moro im going to do the water temp sensor 40fitted. hope it cures the problem. how much would that list of parts above cost? not including a new coilpack.

    for the plug on the coolnat sensor heard it can be un plugged.if the problem stops it means it is the sensor? going to try this now,just read it from another thread

    Well some of the things had been replaced before this problem started, so I find it unlikely that they would have worn out within 6 months. A mate who's good with cars has told me that it sounds like it could be the fuel filter, luckily I've got a spare one in my garage so I'll replace that tomorrow. I only put a new fuel filter in 6 months ago though so I don't know how long they are meant to last.

    Lambda sensor hasn't solved the problem today
  32. #32
    hmmm i got a new fuel filter sitting here, il fit that at the weekend too.
  33. #33
    drove without the coolant temp sensor in fo a bit. was fione for like 15 mins.parked up n it was still doing it but worse lol
  34. #34
    i rember reading some were that the egr valve can cause promlems with poor idle and rough running when its stuck open i think my 2p's worth.
  35. #35
    quite true but mine aint in, I removed it.

    I have a decat on and hope its due to my lambda sensor not been sleeved, if its not that then i'm going for temp sensor.
  36. #36
    Just had a really crazy few hours, went to change the fuel filter and long story short, my arm got covered in petrol, the fuel filter kept exploding off the fuel pipes (I've fitted fuel filters before so I know how to do them) and I got so pissed off with it that I've towed it to a garage.

    Told the guy all the problems that I've been having with the car and the guy said that he thinks the fuel system might be over pressurising, he's going to connect it to his laptop when he gets time. I'll let you know what he says but it might be a day or two before I hear off him.
  37. #37
    any updates, i have a similar issue
  38. #38
    Not sure what a VTS has instead of HT leads but if you get moisture in a throttle body or on any leads between the coil and the spark it willl suck the power right out just as described.
  39. #39
    hasnt done it again yet, had a few starting issues but nothing major, going to get diagnostic equipment from ste soon and have a look myself.
  40. #40
    tried diff injectors.............. same problem!! list goes now as
    new plugs, new coil pack, air filter, lamda sensor, engine temp sensor for ecu, fuel filter, fuel pump, injectors, removed inlet manifold and throttle body(dissmantaled, cleaned, all sensors and connections checked and put back together), plugged in and live running test done, all sensors reading fine!!!! last thing to check is the big relay under the ecu which controls injectors and immobiliser........................ if that dont sort it........ im getting the rifle out!!
  41. #41
    i have got exacly the same problem mate i have changed every thing you have i am now thinking that its a problem with the engine loom or ecu!
  42. #42
    tried a different relay under the ecu (for the injectors and the immobiliser), still didnt fix it!!! which makes the list new plugs, new coil pack, air filter, lamda sensor, engine temp sensor for ecu, fuel filter, fuel pump, injectors, removed inlet manifold and throttle body(dissmantaled, cleaned, all sensors and connections checked and put back together), plugged in and live running test done, all sensors reading fine! im fit to cry!! havent a clue what to try next................
  43. #43
    If its a magnet marelli ECU and ignition system, especially on the west coast's its a know problem for the coil pack to spike the ecu and burn it out. So changing just the coil pack will do naff all, you actually need a new ecu and another coil pack to solve the problem, we got one at work T reg westcoast and its done it twice now so we give in with it.

    For the 1.6 VTR & VTS Year 2000 - 05

    Part numbers :
    0 261 206 860
    96 378 393 80

    Symptoms:
    Common failure symptoms:
    Non Start
    Poor Idle speed
    Stalling
    Revving up and down
    Misfire

    Part number for west coast:
    IAW 1AP.81
  44. #44
    is a 98 saxo 1.4 not a vtr, are the ecu,s compatible with other engine sizes? if it has to be a 1.4, do they need programming? or are they a plug in, plug out job? cheers for the help too
  45. #45
    Depends you can get uncoded replacements, Just plug and play. best thing to do is check you part number on the ecu to thos i gave you. A 98 saxo 1.4 is a west coast.
  46. #46
    So your saying it could be new ecu time?
  47. #47
    Yup, thats what it normally is. Is it doing it all the time?
  48. #48

    its done it 4 times, all about 2 weeks apart from each other.
  49. #49
    Best thing to do before spending 195 on an ecu is to get it checked, i dont mean diagnostic as it wont show nothing as the ecu doesnt know its burnt out, never used them but you could try the ecu doctor who will test your ecu for i think £30 and if it is that they can repair it for 120.

    http://www.the-ecu-doctor.co.uk/

    I aimed the info at everything as a lad posted with a west coast and nearly rebuilt his car hes put that many parts on.
  50. #50
    thats what il try next, thanks for the help dude.
  51. #51
    No problem mate, if you do, make sure you get a new coil pack as that what spikes the ecu. Punto's suffer the same problem.
  52. #52
    does it not seem strange we have all got this problem...

    I was thinking it might be something to do with temperature.
  53. #53
    Ive got a similar problem with mine

    When i first start her up shes fine, though idles abit lumpy but always have done.......after about 15mins, when im stopped in traffic the car will start to misfire and smoke like hell, it smells rich aswell

    Ive replaced the coil pack and spark plugs it did help abit but it still does it.

    Think its time to get my VTR back out to play i think had enough already
  54. #54
    chris i have exactly the same problem too. can you feel like a pulsatin feelin runnin through the car and if you pop the bonnet does the engine shake more as its not runnin right?

    Theres running rough, lumpy idle, etc, then theres a constant missfire, which is when the coil has spiked the ecu. I gave the info for benifit of all members. I dont mean everyone go running out to buy an ecu. I maily provided it for dynebaruk.

    Peasnall if its intermittent, then it doesnt sound like the ecu, as they burn out and do it all the time, Is it actually a constnat missfire, or just lumpy idle?

    Yeh like mine exactly, shakes like hell, tonight it wasnt smoking so much but the misfire was sumtimes affecting the performance

    Havin my VTR back imo the 8v engines just seem more bullet proof with my own personal experience of having 3 VTR's and 2 VTS's (both vts's was like this)

    99 % of the time my cars fine but every so often (maybe every 2 weeks) il get what i described, lasts 20 mines max then its ok?

    i had this problem i took the car apart lol and clean every thing now it is fine

    Just to eliminate any problems with the ecu, is the MIL illiminated? You can try disconnecting the battery over night, not just positive, disconnect both, and leave it over night to re-set the ecu and it will re-learn its self.

    just bought a new ICV will update once fitted
  62. #62
    Garage phoned today, the timing on my car is out and the pulley is cracked. Should be sorted tonight
  63. #63
    same happened to me, was my fuel pump breaking down, so just got a new fuel pump off a mate that had a spare one, and it was fine
  64. #64
    could be ecu problem
  65. #65
    mine was lambda sensor and air box ( not breathing well at all ) fixed it straight away. if some1 comes up with a solution to this problem they will make a mint cos i think its the most common problem on any car i have ever heard of. part of the character though.
  66. #66
    everyone seems to have the same problem, but a different solution lol, so confusing
  67. #67
    Garage did the timing for me and it's still messing about, I'm taking him my old coil pack on Wednesday morning to see if it's that messing up. Sorry if I got anyone's hopes up lol
  68. #68
    one guy on here had the same problem over and over again and went to citeron they did a diagnostic test stil couldnt find the fault, they then replaced the settings on the ECU and everything was fine !
  69. #69
    try fly wheel sencer but normaly the lamber sencer is the one that couses all the running problems but dont by second hand ones get new they are very delicut and can be damiged very esey only about £40
  70. #70
    try a coil pack 37£ plus vat
  71. #71
    At least yours is running lol mine ran intermintent n then just died and wont start at all going to investigate it tomo as i bought it at a bargain price today n hes changed loads n im convinced its ecu fault but hopefully will know more tomo or i might just we shall see lol anyone lese had this problem let us know cheers guys in advance

    Sounds exactly how mine was a couple of months back, kept cutting out until eventually it wouldn't start at all. Replaced the fuel pump and all was fine
    You should be able to pick one up for £20 from a scrapyard so well worth trying before you replace the ECU.
  73. #73
    i had the same problem misfired below 1500rpm took it to main dealer they said it was lamda sensor and guess what just the same changed coil pack yesterday and its fine now.

  75. #75
    No they wanted £190 to supply and fit i got one for £57.
  76. #76
    I had miss-fire, dodgy idle and occasional bogging down.

    Diagnostics tested today, shown up a faulty O2 sensor.

    For the people that dont know what that is, basically the lambda sensor, fitted at the bottom of the manifold before that cat.

    Just to say .. Simple problem when i collected the car i popped the bonnet had a quick check of connectors to find the engine speed sensor just dangling loose from the wire so i placed it back onto the side of the engine (reads flywheel speed) Fireed her up and she ran spot on Bargain car for the sake of plugging something in .. Some people just dont have a clue do they More bargains for those of us who do to

    Just had a diagnostic check, came back with -

    DTC: P0503
    Vehicle Speed Sensor
    Intermittent/Erratic/High Intermittent Fault

    Off to another garage on monday to dig deeper aswel as replace the sensor.

    sounds like mine the nicol in the cat clappsed bloccking most of the gasses from escaping from the back box, i lost alot of power 30%-40%. wen i was driving along the road it slows down its self splutters and fine for a couple of seconds and does it again took the cat off now it runs fine jst waiting on my new cat

    i have sort of the same problem, but mine always seems to be boggy below 3000rpm , really weird problem!
  87. #87
    I also seem to be suffering from this. Mine runs OK once warmed up a little bit, but then if im driving along and i put my foot down, its sort of looses power and then all of a sudden shoots off. Its like it starts loosing revs, and then all of a sudden it starts working again. please someone find out what this damn problem is! About 50people all suffering damn saxo's
  88. #88
    has everyone got an after market air filter on? mines a vtr and thers a pipe tht connects to the inlet (plugs in the standerd airbox at the back on the top part)thats what was giving me sum grief but its running good now i put the standerd one bk on for a couple of days
  89. #89
    mines the same but wouldnt start at all had new fuel pump wil start now and will drive until i put my foot down it taking too much fuel and flooding citreon said it may b injectors if not its your ecu.
  90. #90
    CRANK SENSOR, thats what was up with mine, plus starter motor was dying, both together caused huge problems, getting it back at the weekend, il report back then
  91. #91
    had the same problem had 2 get a new power pack .
  92. #92
    also the seals between the 16v plenium and the inlet mani can leak!!!
  93. #93
    my problem was the coil pack.

    all sorted now.
  94. #94
    My VTS is very poorly, its displaying a lot of symptoms that people have mentioned, it goes initially then all of a sudden feels like the brakes are on, then splutters back into life. After doing all the free stuff (cleaning everything I could on the inlet side, new exhaust manifold and backbox), i'm going to replace the fuel pump and filter, as everything in my trusty Haynes manual seems to point to that. I've got a reciept for a new Coilpack, i'm just worried it could be the ECU thing.

    any update mate?
  96. #96
    FIXED, SORTED PERFECT........................ FINALLY!!! tried a different relay under the ecu (for the injectors and the immobiliser), new plugs, new coil pack, air filter, lamda sensor, engine temp sensor for ecu, fuel filter, fuel pump, injectors, removed inlet manifold and throttle body(dissmantaled, cleaned, all sensors and connections checked and put back together), plugged in and live running test done, all sensors reading fine.
    THEN THOUGH, I TRIED THE ECU AND SUCCESS!!! 1 MONTH LATER AND PERFECT!! PROBLEM WAS WITH THE PART INSIDE THAT CONTROLS THE INJECTORS...
  97. #97
    I'm having trouble with mine, I'm thinking its a censor somewhere that controls the fueling as sometimes it feels like its laking fuel and sometimes for example if I'm in 3rd and go up to quite high revs and take my foot off the accelerator it dies down obviously then gives out a couple of tiny pops as if it gave the engine too much fuel. I thought it might of been the fuel filter at first but I've changed that since and the problem still persists.
    Anyone know which sensor this is and where it is?

    Also anthonyk what did you have to do to your ECU to fix the problem?
  98. #98
    gave the ecu to a specialist, im not sure exactly what he changed, some part that controls the injectors for opening and closing and for duration. well worth a try id say, if your at your witts end, like i was.

    How much did it cost you mate?

    A
  100. #100
    hmmm if this coilpack ive just put on doesnt solve my problem i may send my ecu to the specialist we use at work he's good and i think the turn round time is 2-3 days. not too expensive neither
  101. #101
    Im bumping up an old thread but i think i have the ecu problem, where do i send it and how much???
  102. #102
    Glad you bumped this as mine having same problems so was hoping to find a solution and now looking to see where I can get my ECU sorted?
  103. #103
    Same problem I think mines the ecu.
  104. #104
    Same prob on my vtr. Please don't be ecu!! Purchased a new fuel filter and new icv.

    Could be my lambda sensor which I'll try next if icv and filter don't cure it.

    Keep this thread going as probs a lot of other people having the same problem.
  105. #105
    Here's what I have tried so far

    2nd hand coilpack made it worse so I put the old one back in.

    It can't be compression because its runs fine when cold and hot it only happens on start up. Sometimes it does

    I think this is an ecu problem. A lot of people have replaced the same as you, and still no cure.

    Then they replace ecu and they get fixed. I ain't doing all that list I'm gunna get an ecu if my new icv don't fix this arsehole of a problem.

    Ok so I put my icv in, and it didn't work, the thing is the new icv doesn't cut in, I'm thinking the tsp sensor may have broken as that's what activates when to have the icv cut in iirc, mine dies as soon as I turn the key weather cold or warm, also my engine management light is coming on...

    Make a list what you have tried it will be easier to help.

    mine has done this too now! thought my engine was gone as its on 136k, it wasnt drivable youd rev the car up slowly and it would be a limiter kind of about 2500rpm. but if you put your foot down (parked) it would rev out fine, i turned my key off and locked the car, openned my bonnet up and just pushed all the electrics and airbox about and it kind sorted itself out, but changing down to 2ndgear for a roundabout it would like judder so it must be either the fuel system or the ecu!

    Hi guys!
    I know I'm bumping up a really really old thread! But my vtr had the fuel pump go replaced that was fine then I sent it in for a service came out fine then like a day or so later it's started running lumpy on tick over and when you drive it! It feels like its only running on 3 cylinders most the time! Please help I don't know where to begin apart from I know it's not vacuum!
    Cheers guys!

    Hi All,
    This is my first post on this forum, but I promised myself I would post a solution if I found one, as so many of the threads are opened, but never completed!

    I spent many weeks trying to rectify a bogging down problem and loss of kickdown from the autobox I had with my partners Saxo, which entailed changing plugs, leads, Idle stepper valves, (3x) crankshaft sensors, (x2) Map Sensor, (x2) Coil, removing and cleaning the throttle body, removing and disassembling the engine ECU and the Auto box ECU and all to no avail!

    after 3 weeks of trying I decided to get rid of the car, so bought another cheap little runaround for the missus to use, and on the day of collecting it I received an item I'd ordered that got lost in the post... the cheapest of all of the items I'd requested. (£8) The Throttle Position Sensor!

    I thought it was a waste of time holding on to it, so I might as well fit it, as I could now remove the throttle body in under 5 mins and probably blindfold and in the dark!

    No more bogging down, no more rough idle, no more missing kickdown!

    I blatted it up and down the motorway for a few days and it drove perfectly!
    I hope this helps somebody out, as I would never have thought it could cause so many headaches!
