    I think the problem you refer to was on the Vectra B four cylinder engine - I don't think the Vectra C V6 engine has an idle air control valve.

    I've occasionally had mine idle roughly for five or so seconds and then run flawlessly - I've no idea why though.

    Hi,
    I have 3.2 V6 and this engine does not has idle control valve, there is electric throttle. Rough idle sometimes i have for short time, too. But in my case it is missfiring. Why- i don't know. For me this is normal, now.

    it needs the throttle butterfly and plenubm intake assy cleaning out with carb cleaner..either take it off the car ( buy a new gasket first) or do it in situ...it'll have oil residue in it and this needs removing..

    Thanks for the info, I had a quick spray with some carb cleaner (smelled like kerosene) and the car is running smoother
