Before throwing anymore money at it, try resetting the ECU.

I had this problem on my car (1990 civic) and I went through the motions.
(Cleaned IACV, replaced IACV, sprayed carb cleaner everywhere looking for vacuum leaks)

Tried "pulling the hazard fuze" method (which apparently controls the ECU on my gen. civic) but my idle was still the same.

Then I said, f*** it; disconnnected the battery and held the brakes to drain any residual voltage in the system. I waited about 10 minutes and reconnected.

This lead to the "idle re-learn" process where you let things sit (don't touch the gas) with no electrical load until the radiator fan kicks in. Then shut-off the car all the way off (basically to the point of pulling out your key) and start up the car again.

This is all with my car in mind, it might be a bit different for your car.

Good luck.

EDIT:
If you want to try burping your cooling system, send a PM my way. Not sure if your car has a typical radiator cap setup though.
