a city truck
check this out guys, ever since i put that y8 im on, my car has made this rattling sound sometimes when i accerate, decelerate. or when i rev, does anyone know what that sound is?? i thought it might have something to do with the trans, but it does it in neutral too. i also have a small vacume leak from a shitty im gasket, i'm waiting on one to come from stateside. i guess my question is, is that sound coming from that leak, or what is happening with my engine? anyone???
