hi im new to this so sorry if im doing this wrong but thought id give it a go anyway basically ive got a 106 gti which is running lumpy on idle and seems to have a slight misfire however the car will drive ok if i drive it steady and slow but as soon a i go over 4000rpm then the next time i put my clutch down the car will cut out, it will then start again straight away if i turn the key ignition on off a couple of times almost as if im resetting the icv any help would be much appreciated
parts replaced :
idle control valve,coilpack,spark plugs,throttle position sensor,air intake temp sensor,lamba sensor,coolant temp sensor,purge solonoid valve and ive given the throttle housing a really good clean aswell im guessing the next on the list to change is the map sensor but i have unplugged it and then the car wont run at all or very very rough but will not idle i know this maybe doesnt say that the sensor is 100% ok but shows that it is working in some form just dont want to keep throwing money at sensors when i dont seem to be getting anywhere if anyone could point me in the right direction would be great

I agree with Gibbo.
A proper diagnostic check first is the most important job.Then when the fault has been identified and corrected,clearing the fault codes and resetting the ECU is just as important.
Its a very long time since I`ve worked with these but I seem to remember it takes some time for a new idle control valve to settle down.Some sort of trick driving it through the gears and back down the gears a few times??

Its 98reg and ive had it plugged in on 3 different diagnostic mahines and all 3 are not bringing up any fault codes and i have tried driving it as it is, running throuh the all the gears but still no different like i said before it will drive "ok" when going slow and steady and dont go above 3000rpm but as soon as i rev it over 4000rpm it will just cut out next time i put the clutch down and brake to a stop but if i have it in neutral stationary and rev it above 4000rpm it wont do it

All I can surgest then is for you to find a long established small independent Peugeot/Citroen specialist who has someone who is familiar with these old 16v TU`s.Hopefully they will have the old Peugeot diagnostic kit that may show up something that the other guys have missed?
Or, they may know of some "Peugeot secrets".

I replied to your other thread, but read this too.

If in neutral its not running above 4k, then Id just about put money on crank sensor. Exact same as mine was.
