could it be the vanos or a vacuum leak? crankcase value? slight vacuum when taking off oil fill cap and placing hand over hole.(very slight) my disa valve is working and i cleaned the ICV. (is the icv suppose to move around when you shake it or does that mean it is bad? mine kind of wobbles inside when i shake it.)

Car runs fine while driving...it only acts up when idling.
