I have read a bunch of rough idle threads and talked to alot of BMW enthusiasts. If there's a vaccuum leak the car will have rough idle regardless of which gear it is in. However, for me, it's very smooth when in P or N. But when I stop in R or D, the whole car literally shutters. But smooths out when I give it gas. Already replaced the CCV, Spark plugs, Fuel filter, DISA, ICV, VC gasket, intake boots, and even replaced the fuel pump. Which was not really related. I tried a different set of ignition coils.
And it has nothing to do with it missing the third pedal.
Thoughts?
