had the car in Park in the driveway listening to the engine(cam...I LOVE IT) and i heard a weird almost like rattling noise from underneath car or something. I put the handbrake up and shift to D(3rd) and it "rattles" a tad more?? when i rev the engine up I dont hear it but let it idle back down there it goes again. This isnt the tranny makin the noise is it? thats almost where it sounds like its coming from????? WTF is this noise

check your heatshields on your exhaust.

That sounds exactly like a Y-pipe hitting you're floor board. Lucky for you the TSP Catted Y is VERY adjustable and you can probably tweak it (with a bigass hammer) so that its farther away from the bottom of the car.

but this just started...ive had the TSP catted Y for like 10,000 miles or so. The noise couldnt be coming from something going bad in tranny could it???

Check to make sure your O2 sensors are tight in the bungs. I had a rattle similar to yours and it turned out to be a loose one. Good luck.
