Engine vibrates when idling
How do I stop engine vibration? on 1998 Saturn SL1
Possible vacuum leak. Check engine light on?
Is the engine running rough, or just vibrate the car as if a mount were bad? Exhayst pipe vib. maybe?

1. Check for a 1st or 2nd design motor mount.
2. A updated motor mount is available. Technical Service Bulletin (TSB) #01-T-30A is related and gives mount identification information and mount testing procedures
I had new mounts installed and that did not help.
