I get a fairly harsh vibration in my 02 SE with 6 speed MTX when going from about 40% throttle to 0% throttle and also from 0-40%. Does anyone have any suggestions on what to look for? I understand motor mounts are a possibilty. How do I confirm that's the case? Anything else I should look for? I've got just under 90k miles on the car.

Thanks,
Sari
