    I have problem with idle on Z3M-euro S50...

    Idle fluctuate between 400-750 rpm and sometimes engine cut out...
    Power is okay...

    In drive have jerking to 2500 rpm...

    What is problem?

    @Mnbrennan one for you Martin? I'd be guessing an "air leak" on the inlet side maybe?

    Tony.

    Could be a stopper on the t junction has popped off, on the vacuum pipes.

    Or the ICV needs cleaning / replacing
