help please!!

Dave suggested possibly automatic tranmission setting??

If it has a problem with it's idle it would be more likely to show its face in D or R, as the engine is under a little load, so the idle level would drop.

Just pursue the normal idle 'culprits'.

ditto!!
2 days ago mine started doing the same thing , but the car starts to bounce up and down on the back end until i nock it into neutral, a right bugger in traffic! havent managed to cure it yet, cleaned out ICV also but no change.

have you managed to cure the problem on yours yet ? , as im fresh out of ideas and the only thing i havent checked is the dizzy cap

Air flow metre can affect idle ali. Try air leaks too around the inlet manifold etc

ive replaced the dizzy cap today, stil havnt run it yet as wil do the rotor arm tommorow. so still all loose.

yeah might get it on a CO2 monitor and adjust the Airflow meter thing and see what happens. gets worse as the engine gets hotter!
