my 99 gtp gets a bad vibration when letting off the gas at any speed 30, sounds like something is going to fly out, no shakes. thanks

Look at your mounts...Tranny one is behind the front left wheel, lower motor mount is behind the front right wheel. You may have to pop the clips out for the plastic wheel well shield to get a better look at them.

thanks, il check them tommorro. i just bought the car, i bought a 99 in 2000 and put over a 100000 miles it before a deer at 100+ walked out in front of me. this car has 232000 miles on it and needs some tlc but had to have it, after i bring it back to life im going to start mods. the heads up and raido doesnt work, have a clue? thanks

hey, you were right about the mounts. i replaced the lower mounts and now its smooth, my next step is to get rid of the stock air box, any suggestions on just cone or tubed cone? thanks for info on vibration.
