apparently its running quite even for an ecotec :lol: spoke to the bloke who did the headgasket etc and cleaned the t.b, he said he cleaned the icv aswell and also when he did the head gasket he did a compression test and found it to be ok :S

really annoying my this, the idle isnt like that of a misfire just a minute fluctuation every now and again but i can feel it in the seats / steering wheel etc

do it yourself!

thanx alot for the advice ill take it to the garage again :lol:

Maybe un-even cylinder compression.

Try a compression test too

With the engine running start with cylinder 1 with set of pliers take the ht lead off the spark plug and listen for change in engine noise/drop in revs.

Do that and see which ones make a difference and see which ones dont.

If you have one cylinder that doesnt make a difference when the lead is removed then you know thats where the problem lies.

yes all fixed new egr new dispack new leads new plugs

Been doing it since the headgaskets been done?

no, its just not idleing smooth, but its not showing up on the rev counter, you can also see / feel the engine move when its idling but it doesent do it all the time while idling just every few seconds or so, hard to explain really :lol:

*edit* also jerks when driving in slow traffic in 1st and in 5th on half throttle which is making me think its the icv.. the throttle body has been cleaned today but with no diffrence, doubt he cleaned the icv tho :mad:

Do a compression test then mateysee what it comes up with.

Does it sound rough when idling?

tbh its only started happening after my dispack went and them my head gasket, changed everything else trying to sort it out but no luck so far .. getting on my nerves lately this car :lol:

misfire

could be

CTS
Plugs or leads
shite tesco fuel

Loads of things matey!

if i unplug my lambda and nothing happens does this mean its not working?

what are the other symptoms of a failed lambda? my fuel consumption is ok just the idle isnt even , the exhaust is like spitting air when you put your hand near it

cheers
