Long shot I know ... but ... could you possibly have something interfering with your throttle linkage or cable.

Check out your isc & tps.

Crap like that can be so

Good Luck

When it does this, the idle eventually returns to 1000 RPM or so? If it doesnt, and you turn the car off and restart it immediately, where does it idle at?

Seems like you could put a meter on the tps and look for a clean even sweep of voltage all across the operating range.

Just me thinking out loud as I have never tried it.
