Hello, my car listed above 745i has a rough idle intermittently. I just rebuilt heads and replaced timing chain guides myself. New AGM fully charged battery. Smoked tested and diagnosed at BMW dealership. Misfire on bank 2 5, 6, 7, and 8.
I used AGM timing tools when I set the cams.
Is it possible that the timing is out on the left side just slightly enough to get misfires, but close enough the eccentric somewhat compensates for it?
