    V40 hunting for revs

    V40 is playing up already... driving is fine, car goes like stink and embaressed a few cars...then ever so often the car is embarrassing me.

    Sitting at idle the car drops revs as if it wants to stall, then picks up all of a sudden with the idle control valve. RT's showed no specific fault code.
    I've wound the throttle cable in a bit to help, but it must just wind itself as after 10mins it is back to hunting.

    The changes are 850 single mass flywheel from a dual mass one. We had wondered if the RPM sensor in the V40 need swapping for the one from the 850??
    Any other ideas?

    I would say either the ICV needs cleaning, or the MAF could be playing up, just unplug each one in turn when the car starts hunting.
