ill have to know exactly what its doing to be able to fix it...but its most likely a dirty IACV and an FITV that needs adjustment
i cant tell exactly what it does from your post, give a more detailed desc. of what happens

you need to adjust the FITV, its easy...

edit: thanks the 4th reich aka honda tech ***** for not letting me post an article off another site w/o changing the url....
anyways:

Its very annoying as you may know, but, it is easy to fix, here we go:
Take off the IACV, its the thing bolted to the front of the manifold, two 10mm bolts hold it on, just leave the coolant lines on the bottom, and get a little catch pan to sit over the area. It has two screens on it, take some carb cleaner, and spray as much of the black gunk on the screens out....try swishing some around inside of it, just make sure to drain as much as possible when you are done. BTW, this thing is NOT easily gotten inside of, so dont try that....
Take the FITV off, it is bolted with 3 10mm bolts, to the bottom of the throttle body, you may need to take the coolant lines off to get it out, but once you do, take the gold plate on the back of it off, and you will be looking at an adjustable thermostat. Turn it all the way down (tighten) you will have to push the middle thing in, or just use a special screwdriver setup. Either way, turn it all the way down, then back out 5.5 turns. This adjustment controls the amount that the valve flows at diff temperatures. I have found 5.5 to be the best area, but you are welcome to adjust otherwise, but i can assure you that 5.5 worked for me.
Now check all of your vacuum lines, making sure none of them have cracks or holes in them, you dont want leaks.
If you still have a problem you either have a bad IACV (which would trip a CEL) or you have a vacuum leak somewhere on the manifold</TD></TR></TABLE>
