    At idle (i think when warmed up) the engine is not sat at a certain revs it hunts up and down, only very slightly BUT this causes a ever so slight vibration that can be felt through the seats.

    Is this normal, if not what is the likely cause. I was thinking a dodgy MAF could cause it.

    mine does this but without the vibration.

    On my clio 172 a few years ago the vibration was the exhaust middle section not sealed properly to the cat

    is your air con switched on this will always cause the engine to hunt or idle irratically but slightly. anything else could be throttle body, air filter, MAF.

    This can be caused by a vacuum leak. Check all your vacuum hoses for tears.

    To all that have answered that yours does it to.

    Can you feel the vibration through the seat when sat in it ?


    The only reason I ask is I had a 306 that did this once when the cambelt let go and a couple of valves got bent ever so slightly and ended up with me having to sort it.
