here's the history first: i have a 94 gt with 182000 miles. i have spent about 2 weeks installing long tube headers, new oil pan and oil pump, new radiator, and other little things that i found along the way that needed to be fixed. I did replace my power steering hose, the pressure line, due to it being cut by a pulley. No big deal, bought a new one and replaced it. After i checked everything several times over (after learning from the previous incident), i noticed the other day while driving it that there is a vibration, not a big one just enough to be noticed (this wasn't here before the 2 week venture to hell and back, i.e. headers). I can feel the vibration while coasting in neutral and while shifting through the gears, i can feel it in the body (when i put my hand on the floor board) and the steering wheel. could my headers be touching somewhere i'm not seeing? i'm at a loss as to what to look for, so any suggestions, comments, or questions would be great. If you need more info, just ask, i'll try my best to explain.

thanks in advance,
Gerald

Are the engine mounts or Trans mount weak?

Are you feeling it at any certain RPM or MPH?

I'd make sure the headers or other parts of the exhaust aren't rubbing the body somewhere. Also, have you tried neutralizing the eng and trans mounts and the exhaust. Try this, loosen up the h-pipe at the long-tubes and the tailpipes at the h-pipe. also loosen the motor mount nuts and the trans mount nuts. Put the car in a fwd gear and while holding the brake, try to go fwd. do the same in reverse. do this a couple times and then tighten the loosened bolts in this order-
1) eng mounts
2) trans mount
3)h-pipe to headers
4)tailpipe to h-pipe
this should help
