Sometimes......I hate driving my car! Here's the situation: (B16A w/CTR cams and bolt ons in an EH3) With the motor up to temperature (never does it cold) the idle hunts after acceleration and goes back to normal idling after 5-10 seconds of hunting. No codes at all. What I've done: Cleaned the IACV (which wasn't dirty to begin with) Bought a new OEM FITV (torqued to TB @17lbs) Switched TB to one with a for sure "good" TPS on it Unplugged the IACV at running temp and the idle didn't move (Helm says idle should go down or car dies) Reset the ECU Burped/Bled the coolant system after doing the FITV What I figure it "might" be: The USDM P30 ECU is faulty.....? (I dont think so) The IACV is bad (torn between a junkyard find and spending the $200 for a new one from Honda) Could I have a vacuum leak? Don't feel or hear one but maybe someone has a tip to help me? My gut tells me its the IACV and FITV fighting eachother Let me know any thoughts you might have!
