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!
