   i have a stuttering car. i no they run laim and have a slight bump on tick over.
   this car is a s reg vts with full stainless system and pipecross filter. have checked the back box+system no cracks, have fully serviced it including plugs oil and a bran new coil pack. i have also changed the lamber/o2 sensor. it seems to have a loss in power when at low revs ie; 4th at 30mph, when reved it goes like stink. i hear it could be a faulty lamber/o2 sensor or as i have changed the coil pack it would of put a error report on the ecu.. any help its doing my nut in?????

   Can you explain the stuttering in more detail?
   
   A VTS will not give you much pull in 4th at 30mph normally anyway.

   That's probably the exhaust system. Is it a de-cat system? My 106 seemed to have a rough idle with standard camshafts, which was down to the exhaust system... So where do you feel the block in power? You have mentioned that when you rev it, it goes well.

   its more than rough it shakes, you can see the car wobble, exhaust is a cat back system, was has been on it since new and has been fine. just dropped it off with a mate who was a wrc mac for ford, he says garage fitted a universal o2 sensor, he has got a cit vts one and is fitting now. says its def the shitty o2 sensor, will post results in a few hours when i get it back.

   the block in power ie the stutter is when cold and when setting off between 1000 and 2500 rev, mainly fuel saving gear changes

    wow someone has actually got the same problem as me! like you say its just like someone switches off the injectors! it only does it when cold.
    
    my idle is the same too. really wavey and also cuts out every now and again too!
    
    what is it?

    LoL! Dan, you should be reading my progress thread, as you're not alone!
    
    That problem used to occur on my car when it was cold, but it's constant now. And, I even have problems in the higher revs!

    Think im suffering similar to you guys too, except mine seems to run alright when its cold and the idle goes lumpy once the engines up to temperature. i'll go have a read through ur thread toad.
    
    I reckon im making a loss of power low down the rev range & probably am in higher revs too, i rarely drive it fast so i cant remember how it drove before but im sure my last VTS packed a harder punch right from 2000rpm

    Mine is exactly the same mate. Ticks over fine when its cold, but goes lumpy when its warm.
    
    Mine still goes ok throughout the gears though, haven't noticed any drop in performance.

    Yeah same here. Very occasionally, it cuts out when I'm coming up to a stop and press the clutch when I'm still rolling. Its embarassing!

    Not necessarily though Toad, the same symptoms over 4 tu5jp4 engines, maybe its something all the cars have in common which is causing the issue?

    there have been numerous posts in the past on this. its a common fault. cars have been on the diagnostics at citroen and still cant find what the fualt is exactly!

    Yeeh iv read a few over the years too and theres a huge list of parts people have replaced to sort it too. I sort of thought it was an ECU issue but since both of you have had remaps im not so sure it is now

    Fair point chap.
    
    Well, I've certainly covered a few angles, those being the O2 sensors and the MAP sensor...

    I've got a spare coil pack to try but the coil pack is from a 3 plug & mines a single & the plugs on the coilpacks are slightly different, i've been debating whether to just file the plastic plug down so it fits
    
    
    One on left is my pack, one of right is the one from the 3plug saxo, its got an extra notch down the middle of the plug

    It's likely that's there for a reason then. Although, I couldn't say for sure.

    changed the lambda and its sorted! well the lack of power and ststtering is. it still cuts out everynow & again when up to temp though...:s

    the stuttering and lack of power when cold. i changed the lambda when i changed my manifold and it idled really crap since then and when i 1st started the car it wouldnt let me rev it above like 2500rpm would just splutter! but now iv changed the lambda back to the one it was mapped with its sorted that!

    #34 3rd August 2007, 13:29

    Oh I see! Interesting... My car has been running with a faulty lambda in the exhaust manifold for god knows how long!? And I changed it the other week and I haven't noticed any difference whatsoever! Shocking! I've also changed the MAP sensor out - No difference! So in theory, I could run my car with no lambda sensors or MAP sensors and it wouldn't make any difference at all - Which is shocking!

    Just to add... When I start the engine from COLD, I always leave it ticking over for about 1 to 2 minutes, as if I rev it, it's very rough. Also, during this time, the air injection systems is (meant to be functioning - I've taken it all out now...) so the ECU is none the wiser. I know when this is over, because the revs flick up briefly, and then settle. I then drive off... lol.

    see i thought the cuttin out and the bad idle stuff was down to the mixture and that. and on older cars the auto choke would cause it. is this not the case for saxos? do they not have lik auto choke?

    #37 6th August 2007, 22:06

    Yeah, most modern cars have that. When I start my card from COLD, it will idle like a pig, then after about 1 minute, it will be perfect, then 1 or 2 mins later, it will be a pig again. It's a shame it can't stay how it is after that 1 minute period! Bugger.

    With a proper setup with TBs and a good standalone, you can a decent idle if the operator know's what he's doing...

    try a map sensor. my mates 106 gti used to be fine when cold and when got to temperature it would hold back when he pulled off an then suddenly shoot off. it had a rough idle to. he took it to peugeot and they diagnosed it as a manifold pressure sensor. its all sorted now, like new!
