Reply With QuoteDo you have a rough idle when warm, cold? How many miles? Have the O2 sensors been replaced? Also could be a vacuum leak.

540i/a running rough continue's
my 540i/a is still running rough. i had the local dealer check it out today. their computer found no fault codes at all. they suggested it could be bad motor mounts. has anyone else had a problem with bad motor mounts causing a rough vibration in the car. it is worse around 1300 r.p.m.
thanks

what problem did you have with the pcv plate?

it got to the point that it couldn't get to 40 mph, a crappy idle, a intermittent miss and one thing that was really weird, the computer was trimming the mixture 25% lean on one bank and 25% rich on the other from the baseline running setting, we could reset the computer and it would be screwed back up in a couple miles of driving, another weird point no check engine light. there was no external vaccum leak, all internal
