Bought a 05 civic about a year ago with a snapped timing belt. The car was being used and DD by previous owner up until the belt broke. I bought the car and finally was able to get around to doing the belt. Everything is fine except when i start it it has a hunting idle. It hunts from 1200-2100 rpm. I have no codes at all. I pulled the IACV today and cleaned it and it didnt fix the problem. I dont want to just keep throwing parts at it so I wanted your guys' opinion on what to check. Its been sitting for over a year and im pretty sure the previous owner didn't drive it like this. There doesn't appear to be any vacuum leaks. When i disconnect the TPS the idle shoots up to about 3k and stops hunting. It hunts regardless of a cold start or it being warm. Thoughts and suggestions appreciated.

The car runs and drives fine except the hunting idle btw, timing is not off, coolant is not low either.

 

damn HT aint filled with knowledge like it used to be. Miss all the old head EM1 owners
