At idle, in gear (forward or reverse), my 2002 3.2 TL-S has an ungodly vibration and loud "hum" (by hum I mean the type of omnidirectional booming like when you pull up beside a big truck or bus - or a boom car). Gives me a headache. This can't be normal.

 

Sounds like your mounts are bad.

 

Thanks, I appreciate the response. I had not thought of that. Rather, I should say I would not have thought of that, on such a new car.
