Re: 2003 Pilot Idle Surge Hell (P0505)
UPDATE: I bled the cooling system (no air, but hey I ruled it out).
I put my hand over the throttle body itself. Car stalls. No vac leak after TB I would say!
I then completely sealed the IAC-v hole before the throttle blade with duct tape. Car idles perfect. I then sprayed throttle body cleaner at the closed throttle blade (while iac-v hole was sealed closed). Car stalls. Possible issue with throttle body valve itself!?! I'm not sure how "sealed" a closed Honda TB is supposed to be.
Anyone? I'm left with:
Bad throttle body itself/replace the whole TB
Bad IAC valve from Autozone
