I have a 95 contour GL ATX with the zetec. I was wondering if anyone can help me with this problem... when the car is in drive and you are stopped it shakes really bad, it gets like 10x's worse when the a/c is on. The vibration goes aways once you start driving. I've had it looked at by a few mechanics and they seem to think its the motor mounts. I replaced the passenger hydraulic mount and the front mount and still no luck! Also found the belt tensioner was busted up. Replaced that. It got a little better. What the hell could it be? Should i replace the rear mount and the tranny mount??? Someone suggested it could be a bad harmonic balancer...
