Car vibrates when stopped.

BM91 · 01-29-2015, 02:25 PM

I noticed that my car vibrates more when the AC is on when I'm stopped. When I turn off the AC all is good and is idling normally. Does anyone have any ideas? I just recently changed the Sparks and serpentine belt. the issue were there before getting them replaced.
Thanks

I have the same issue. Dealer replaced all six coils. Now i don't wanna say that work cause at times it would be fine then sometimes the vibration would come back.

I have noticed a bit more of an inherent engine vibration on extremely hot and humid days(with the A/C on), but this is only on a few days of the year. Vacuum leaks is where I would start for an off target idle.

I've had this issue with my 325i. Inspected spark plugs and coils. Changed spark plugs out and didn't happen again for another 40K. Replaced them again and it went away. haven't seen it since.
