1999 Accord V6 Coupe. *Started with a high idle, about 1000 RPM when in gear and 1200-1500 *in Park or Neutral. *Took the original Denso off and the little flap door was stuck open. *Cleaned it real well and reinstalled and then the car was idle hunting and bouncing between 1000-1500 PRM in park, time for a new sensor. *Picked up an "Intermotor" brand which is made by BWD, and basically looks like other "China" parts I have bought online. *Installed it and the idle hunting went away, but high idle still remains. *Took it back and exchanged for it for another one in a "CarQuest" box, same issue.(I think it is still a BWD part.)
Plug is getting power at pin #2 and there is continuity between it and #3 as the manual states to check. *With the new valve installed if I put a piece of cardboard over the IAC inlet hole in the throttle body, idle drops back down to normal where it should be ~6-700 RPM so I know the sensor is the culprit and there are no other VAC leaks.
Anyone have experience with other brands? *Is an OEM Denso the only way to go?(At $175 online!)
Not my throttle body, but for reference
Tried two of these valves, same issue as the one that is stock and stuck wide open.
Car feels like it wants to take off with the foot on the brake lol!
