It is probably the FITV or even the IACV, there are write up's on how to check.

Its a white screw/round thing that is right infront of you when you open it up, it usually turns itself all the way out, causing the car to idle high. Get a flat-head and screw it back down. I think you are suppose to tighten it, than open it 3/4 of a turn or something. Read a write up for exact specs. But unless its a obvious vacuum leak, im 95% sure it would be the FITV causing it.

**found it:http://www.honda-tech.com/showthread.php?t=1564019**


Does it stop doing that after about 30-40min of driving? Once the car is fully warm?
