Im guessing its the engine mounts or something.When I shift from first to second gear the engine slams back pretty hard.Its does hit anything but you can feel it kick back.That and if I suddenley let off the gas.

Does that sound like the engine mount?

 

Sounds about right. Poly kits are cheap and work well but transfer vibration a lot.

 

same prob here...i got some energy mounts for like $20 bucks on ebay....i'm pretty sure they're easy to find elsewhere too...

 

Anybody know if those TEIN engine dampers will make up for the vibration at idle?Or are do they serve a different purpose?

 

replacement oem or motor mount inserts are the ONLY things that will fix your problem...as well as maybe 3m window weld
