Broken motor mounts
 

I did the timing belt on my 04 and had to replace a broken side motor mount. I notice when I drive the car the motor seems to put off vibration so I'm gonna assume I have at least one more broken motor and/or trans mount. What's a good way to diagnose broken mounts?

If the engine is rough, visually check the mounts.

Get a helper to put the car in gear both D & R while you watch the engine. Have them hold the brake while in gear and rev the engine. You'll be able to see how much play is on the front and rear mounts.
