I installed new motor mounts and tranny mounts and I now have a slight stumble whilst idling on my '01 540i sport. When I start it cold it more pronounced than after it's warmed but still can be felt. Also I do not see the tachometer bounce around.

I have no lights on the dash nor is the performance/acceleration affected.

The transmission shifts smoother with the new mounts.
