Got my b16 swap in my crx finally done and its got a weird idle. At first It threw code 14 IACV and I realized that it wasnt plugged in. I have cleaned the screen on that valve and the idle still bounces from like 1,000 to 1500 rpms'. NO codes anymore but it still does this. I have bled the coolant system several times and that did seem to bring it down a bit. What about the adjuster screws on the TB? How do you go about adjusting these? What other ideas do you guys think this might be?

BTW, its a b16a obd0, pr3 ecu

 

Have you tried swapping out for a known-good IACV? I had this same problem, fluctuating idle, no codes, cleaned it and it still did it. When I swapped it out for a different one, all was fixed.

 

the screw on your throttle body? you just stick a screw driver in there and turn it in to lower the idle or twist it out further to raise it.

 

Did you reset you ecu and let the car idle ( don't touch anything ) for 10 mins after wards ( or until operating temps have been achieved )

 

The problem here is the fitv... Take it apart and screw the screw in and it wont happen anymore. do a search for FTIV...

Sure will. The only thing that is it wont hold at 2k rpm when you start it up cold, but if you dont drive in the winter or live in a warm state it really doesnt matter...

 

to see if that is really the problem,temporarliy block it off with some thing.loosen it up and slide a piece of a ceral box in there and tighten it down,it will most likely go away.i have had to replace several of these *******.
