Thanks for the advice... I think replacing the other mounts is what i'm gonna have to do cause the vibration is so annoying and I don't know what else to do. As far as a tune-up, I did one like 2 or 3 months ago... a complete tune up at that. Funny thing I just remembered, the salesman who sold me the car told me that ALL contours shake and vibrate. I didn't believe his lying ass but I wanted the car anyway. Anyone else have the same problem i'm having?
