Re: idling problems

I get the same with my M20. It's done it for years and I've never got to the bottom of it.

Re: idling problems

would it be a idle control valve or a air control valve?

Re: idling problems

i,c,v will play up from cold.it may be the air flow meter.
or a split air intake hose to the throttle body.or any of the breather pipes around
the rocker cover and inlet manifold.
i'd check these first. emoticon

Re: idling problems

There might be a vacuum leak somewhere, you should be able to hear a hissing noise when the car's idling if there is.
