1990 735i Noise When Slowing Down or Idling

[jrs811]

I have a 1990 BMW 735. I have begun to notice that when I slow down and come to an idle (at a stop light) that there is a noise that vibrates a bit up the steering column. The noise goes away if I shift into neutral and rev the engine. Also, there is no noise when I am at higher speeds--it only appears when I slow down or come to a stop. Can anyone help me figure out what this is? Thanks!

Check the motor mounts. Something in the engine compartment or the exhaust system is making contact with the chassis.

may be the geabo if it has one or trans mounts.
