This has to be a TPS problem right?

Ok, so my car, when started rev's to about two grand, then settles into a normal idle....
If I'm driving down the road, it tends to buck a bit until over 2000rpm, and then runs fine.

If I take the car out of gear, and am coming to a stop... the rpms drop to like 400, and then once I'm stopped, they go back up to a regular idle.

Car also randomly dies when at idle.
Any ideas?

Tune would prob help and btw you have 3.42s.. if you have a 99 trans am m6, you don't have 2.43s unless you put them in yourself?

Vacuum leak maybe? My car had similar problems until I fixed a leaking vacuum hose. Now it's fine.

The reason I think it's TPS, is because it seems to be related to the speed I'm going..even when not in gear.
For instance, when I take it out of gear, and am doing 60mph, the engine rev's to 1500, stays there.. as I slow down.. rpm drops, when I'm at 10mph, the car is barely running, at like 500rpm.
I don't see how that can vacuum related.
