Then disconnect your battery for 15 minutes, plug the iac back in hook the battery back up and start and idle the car until it idles steady again at that point it has "re-learned" the new idle and will idle where ever you want it to. If you go through the whole ordeal of setting your idle correctly make sure your tps is still under 1.1 also before you disconnect the battery because if it isn't then when you hook everything back up the computer will neveer go through the proper idle learn procedure. Also it is amazing how smooth you can make even an E-303 idle by doing it this way. It will still sound like you have a cam but 99% of the hunting and surging will be gone.

That doesnt work for everybody, I had surging idle issues and tried EVERYtHING, including what you describe with poor results.
