Vibration at 1100-1400rpms

Hello, I have been trying to diagnose a little vibration I get when coming slowly off the line. I ruled out tires/wheels/suspension and have narrowed it down to an engine vibration. When in P, N, or D the car will have a slight vibration (felt through the steering wheel and floor) between 1100-1400. If you hold the RPMs here it will continue but once you exceed 1400rpm it disappears.

Any ideas what would cause this? BTW- This is on an 07 CLS63

Thanks!
Alex

Busted engine mounts could cause the vibration. Just a guess.

I thought about that as well but in that case wouldn't the vibration magnify as the RPM increased? Also, I had a friend hold the RPM at 1300 and the motor does not seem to be shaking at all.
