C20xe coil pack type...
It misfires/ judders astho it looses the position of the pedal or fuel for a second, only happens at a steady speed, so revs at still, it's fine when giving it some, but it does it now and again,
Have changed the afm, fuel pump and spark plugs any other ideas? I was thinking throttle position sensor??
Cheers

Tried getting hold of a coil pack but seem to be different, also now tried coolant temp sensor, that didn't sort it

Had a look for leaks and loose connections and carnt find anything, was going to change coil plugs and leads yesterday but I have the problem again of not being able to find cylinder one lead long enough,
It does bring the light on as it judders and goes straight off again but don't seem to show the code for the problem, whether that's to do with dif engine in the car,
Lambda is prob fairly old, so that's prob another thing on my lost to do now,
Tries dif things while driving, it seems when I go over bumps while the foot is steady in pedal, and if I coast it don't do it or slowing down with no foot on pedal again don't do it, I thought loose connection but could it possibly be throttle position sensor?
Think I need someone stripping same engine and get everything

its wierd that the eml comes on but doesnt store the code, i always thought a code remains in the ecu for a while and only clears after quite a few "clean" runs (when the engine has been started and stopped without the fault reoccuring).
May jus hafta go hunting round doing things one by one! Could be a broken wire somewhere, i had a wire to my AFM that had brokien jus where it goes into the plug under the rubber seal. Took me ages to find it
