Car vibrates like crazy
Car vibrates like crazy 1998 Firebird 3.8 v6, auto. New motor mounts, transmount, new plugs and wires, new harmonic balancer. Ive tried everything trying to diagnose this thing. Its my daily driver. It seems to vibrate when the engine is under 1000 rpms at idle. Doesnt matter if the car is in park, neutral or drive, doesnt change vibrations with switching to reverse park or neutral. As soon as you rev it up past 1000 rpms the vibration goes away. Its not throwing any codes. Tried putting a jack under the Kmember and then under the rear diff just to see if changing the angle of the drive train had an affect and nothing changed. Even put the jack under the exhaust just slightly to see if maybe it was hitting somewhere on the body. Im out of ideas.
I was thinking maybe a clogged cat or torque converter on its way out, but i thought those would throw codes or my cat would be getting really hot.
Vacuum leak would throw codes too right?

Did you get the hydraulic trans mount or the solid rubber one? The car came from the factory with a hydraulic mount and when they go bad it vibrates like hell. The only place i have found that sells the hydraulic mount is the dealer.
The hydraulic mount. Cost me 40.00 special ordered from Oreilly. I had a trans mount go out in my manual transmission car and the trans would slam against the body when I'd shift. This doesnt do that. It just vibrates like crazy. But maybe the A4 wouldnt slam like that?
