My 1995 SRI Ecotec 2.0L 16v Cavalier is giving me some trouble.

When the engine reaches running temperature, it start's to rev itself up to 3/4k and back to 1k. It keeps going up to 3/4, down to 1 continously.
The only way I can stop it is to rev the car past 5k and then it will stop. I could drive 200 miles and it wont return.

Once I turn the car off and then start it again when warm, it just start's the reving up again.

Any ideas? I've changed the idle control valve and tried a different TPS, both have not solved the problem.
