Rattle at idle? I've had this rattle coming from my 99 z28 since I got it, and it's driving me insane.
It's only at idle after the car has warmed up a bit, and it seems to go away above 1500 RPM or so
I've tighten all the header bolts, all the accessories are new, the car has LT's and duals
It sounds like something is loose and is quite loud, it is especially loud underneath the car
it's kinda hard to hear, but after 0:36 in the video is when it is the loudest

If it sounds like its coming from everywhere, the bell housing is a good place to examine with a stethoscope(or makeshift version). Since its in the center, the noise can travel in most any direction and is hard to pinpoint. Access to a lift would be a huge advantage in narrowing it down.
