i have a obd0 integra that i just recently fixed fitv on and the car still idles at 2k when you start it and it drops to like 1250-1500 after it warms up and sits there. but after you let it idle for about 5 minutes itll fluctuate once or twice from like 1650-1000 then itll go back to idling at 1500. So i plugged the iacv hole in the throttle body half way and the rpm dropped to like 750 and sat there and didnt move anymore i dont understand lol..

i took the iacv off before and the screen was VERY clean so i didnt clean it out and i screwed the white ring in the fitv all the way down when i took it off to fix the old surging idle. It was completely off the threads thats why i screwed it down all the way but anyways if some1 knows what else i could try to fix the damn thing lmk!

 

did you unplug anything, like your tps sensor or your map sensor? I ask because you could have gotten them mixed up and plugged them into the wrong spots. Or your tps sensor is broke.
