Hi, I just put a used low milage 3.0 engine in my 2000 ex accord.{new timing belt-water pump-adjusters-spark plugs-oil- anti freeze-and burped the system -it sounds great... I tried the upper plenum off both engines {the old engine broke timing belt but ran great until that happened } it has a cold start idle of 2000 rpm then when computor takes over it surges between 1200 to 1900 rpm continuisly- eventually it sets a code 0505 I checked for a vacuum leak with carb cleaner and smoke-- nouthing... Is it possible for both iac valves to be bad-- I also checked the iac by disconnecting the one on the car and hooking up the extra one{ in my hand} and I don't see anything moving inside it--does the rod move in them? It isn't very dirty inside either.. It doesn't seem to me that both iac valves could be bad-- what do you think...
