VIBRATES OR SHAKES

2001 Pontiac Grand Am • 136,000 miles

Vibrates when stopped at a red light and in drive and park - put in nuetral and goes smooth - When idling it is only at 600 rpm's - Replaced all 4 motor mounts and tires and tie rods and some sensors.

That's typical of a long-overdue tune-up which mainly consists of new spark plugs and wires, depending on which engine you have.
