Idle to low?
Also we just had a truck in our shop where the damper spun. Check that out also

What tranny? I wonder if it has the wrong imbalanced flywheel?
Vacuum leaks?
Describe the vibration better. What RPM, is it buzzing or shaking etc.

My 300 seems to like a higher idle speed than the 360 I had.
Then again, the broken motor mount is probably not helping much.
Vacuum leak(s)? Any uncapped ports? Many have also had trouble with faulty condensors.
