I think I posted this a while back, but i guess ill repost.

Havent been on the forums for a while, but...

I have a 1991 300zx n/a.

When im at idle, my car shakes. not violently, but enough to feel it enough to annoy me. I can actually see the my hood shaking lighting while sitting at a light.

while this happens, SOMETIMES, i will hear a rattle from the bottom of my car, sounds like the exhaust, but i cant be too sure.

this only happens when im at a light. I can be in drive, reverse, park , or neutral and it still occurs.

my RPM is usually below 1k. i have read up that it could be compression issues with one of my pistons, and possibly a piston not firing.

any ideas? i wanna get this fixed asap!
