Did you compare the old mounts vs. the new? I ran into the same situation with my Daytona. Side mount was completely torn, engine mount ripped and trans. mount twisted badly. Replaced them all.

The 2.2's usually idle a bit rough, but mine was like a diesel! I double checked to ensure the engine was level & center and it was fine. It wasn't until I compared the old mounts to the new.

The new are virtually solid. The old ones, the pin in the middle of the mount is suspended by four pieces of rubber. On the new, it's cast right into a block of rubber.

Over time, the harshness has diminished. I think as the rubber breaks in, it allows a little more flex.
