    S600 W220 misfire when NOT driving

    If I try revving the engine whilst standing still it will not rev above 2300 -2500 rpm without trying to cut out, when I'm driving there's not a single problem with it, idling is smooth and when on the road I can floor it and doesn't miss a beat no loss of power, any ideas anyone?
