  1. Rough Idles and Misfires in Cylinders 1 and 2

    E90/E91/E92/E93 (2006 - 2013)
    Background: Car was misfiring last week and had oil in spark plug holes so I changed valve cover gasket, OFHG, ignition coils in cylinder 2 and 3. I do not believe the VCG is leaking, although that is possible. I checked it a few days ago and it didn't appear to be leaking but its hard to see...
