Default Rough Idle

Hey guys,
My car used to be rock solid on idle but now it seems to dip up and down to 200rpms but never cuts out. It doesnt always do it as well at other times its rock solid again. strange
Has anyone got any ideas?
Thanks alot
Miles

Hello Miles,

when were your sparkplugs replaced / last service done?

The 40k service was done last April, which was about 5k miles ago.

On the C2T's the ignition will retime (advance or retard, don't know) to try to catch a dieing motor.

An over rich setting can also make for a motor that "hunts".

And the Lamda computor can fight w the O2 if CO is off.

On my car the clamp that holds the 90 going into the turbo can slip off.

Maybe start by checking your CO.

Replacing my injectors seemed to help my idle quality and picked up my low end running also.

My $.02 and not worth a penny more.

My advice, worth even less then Keith's.
Agree with Keith, start with checking CO, not impossible that it's to lean.

OK thanks guys,
Keith you said the 'clamp that holds the 90 going into the turbo can slip off'

Well I think I have a problem with my turbo feed pipe as it smokes alot from there sometimes as well when the car is at an angle and also it has had it replaced recently so I guess i will check that.

However I didnt quiet understand what you meant about the clamp??

Cheers alot
