I assume you are letting off the gas when you push the clutch in?

Sounds like a TPS or IAC issue to me.

I've driven a few cars that did that. I always assumed it was to aid in smooth shifts. Kinda like rev-matching for the next gear.

Do you have any aftermarket modifications, like a cam that required drilling a larger hole in the throttle body? Engine will rev as long as it's getting air. Let it rev. Might want to check into the tuning and stick to premium fuels.
