2001 park avenue engine shakes

I have a 2001 park avenue. Runs great but when you take your foot off the gas it feels as if the engine shakes or moves. This happens if driving or just parked. Maybe worn motor mount? Looking for ideas. Thanks :grinno:

Just in case anyone else has this problem turned out it was a bad motor mount.

I have the same problem with my 2003. I replaced the mount in the front of the engine compartment, near the radiator but the shake is still there. Which mount did you replace?

Yes replaced that what a difference.
