   Ignore origional post
   
   Never have problems with the car cutting out under normal day to day commuting. however when ever I go out and have a bit of fun in it the next time I stop at a junction etc it will either be really spluttery and try to cut out or just cut out straight away.
   Always used to think it was a slightly dodgy idle stepper motor but im not so sure now I know its related to how you drive it before hand
   
   
   
   New post
   
   back to the top as the problem has returned
   
   
   took it in for diagnostics testing and the only thing that came back was low voltage on the lambda sensor.
   
   Replaced this and it was fine for two weeks including a weekend away at trax. still a touch lumpy on idle but no fluctuations.
   
   
   But now in traffic this evening its started acting up again :|
   
   
   hasnt cut out but the revs flutuate and it feels very lumpy. and when you dip the clutch when pulling up the revs either drop before going back to normal or stick at 2k before dropping back.
   
   Again only does it once warm
   
   
   I have replaced the tb and all sensors
   
   lambda sensor
   
   
   Back to the old faithful coil pack? as I assume this wouldnt have shown on the test
   
   
   
   
   Suggestions on a postcard please
   
   
   It was good while it lasted

   Would this sort of thing show up on a diagnostics test? As no eml has come on or anything. Just dont want to get in the visious circle of changing parts until I find what it is

   Just purchased a complete throttle body and all sensors from a member on here so will try that. as that should rule out a few things.
   
   
   Where is the map sensor on the late VTS engines?

   what year is it?, ive a 97 VTS and the map sensor is on the left side of the inlet manifold as ur looking at the engine., should have a plug with 3 wires.

   took the plugs out and they looked ok. Is there a way to test the coil pack before I shell out on a new one?
   
   
   As the for fuel pump if any thing its running rich rather then lead. But I think thats because the car has a super chip

    Have you cleaned the idle control valve and associated breather pipes yet?
    Low voltage at the lambda - does that mean the lambda is not getting enough power for it to work correctly? If so replacing it would not solve the problem if you look at it that way. May suggest corroded connections or poor earth some where causing resistance? Its not unheard of to have a fualty ECU as weel, long shot though I know.
    
    Just a few idea for you mate. Hope you get it sorted!

    The chap that did the diagnostics recomended replacing it. So thats what I did and I cleaned all of the connectors as course of practice anyway.
    
    Going to clean the map sensor tomorow.
    
    
    ICV and the tb are still squeaky clean.
    
    Will do the breathers as you suggested too
    
    
    If I pop the coil pack out is there a way I could test it?

    having a very similar problem, i have changed, throttle position, map, coolant temp, idle control with no luck.
    going to try a new coilpack
    
    although i think i have a bad earth on the gearbox

    erm not 100%
    
    
    put on a new coolent temp sensor and coil pack
    
    
    Car runs fine for a couple of weeks then will start going crap again. Reset the ECU and it will be fine for another couple of weeks
    
    
    Fudged ECU maybe?

    have the same problem fine when cold but once i have been driving for 15 mins + and it warm. revs nearly cut out when braking hard then catch themself and gets lumpy to.
    
    had a new temp sensor fitted, lambda, icv replaced all this week and full service as well
    
    not the cat as mine is de catted

    Right although mines not a vts its a vtr about a year ago when the engine got hot it would cut out or run lumpy,then not start until cooled down so I bought a used coil pack & have never had the problem since.

    Still having this problem have changed over crank sensor, tps, map sensor, coilpack, lambda, temp sensor, throttle body, throttle temp sensor, icv.
    
    Switch all the above over with other ones i know that are workin and still none of them have helped to solve the problem.
    
    when warm its the worse coming up to lights the revs will dropped down and sometimes stall if i don't catch them and when cold feels rough to. once you go over 2k it drives fine no problem just down the lower end of the rev range.
    
    any ideas ???

    have you checked the pipes going to the inlet manifold for splits? also the fpr could be faulty or the fuel pump underperforming

    #19 9th March 2011, 14:33

    yeh forgot to say all the pipes going to the inlet were replaced with new one's.
    
    i thinking could be either injectors, pump or relay is there any way to test these ?
