well yell03, i dont know how many replies you might get on this, but personally so many little noises and rattles and vibrations come from my car that maybe its natural. Did it do it when you picked it up? or after exhaust mods? I dont know, turn up the music?
Is this the rattle that seems to come from behind the radio or console, but you cant really tell where it comes from especially going over bumpy roads? This is most anoying, but I cant seem to track the noise down. My 90 GT had the same darn rattle. I never did find it.
