9 months... full-wire tuck... some boltons... and the extraction of a turbo kit later i finally get my b16 crx runnin.... BUT once warmed up, she idles at like 3k. So far thats the only trouble i noticed.. And 2 codes. oxygen sensor heater. which can suck my *****, and the IAC code. Which is probably my reason for this high idle issue. How do i go about fixing this code? Or what steps do i take to solve this issue?

thanks in advance!

 

pull your iac off the intake manifold, spray it with wd40 or some other form of cleaner, reinstall and see if that helps, make sure you unplug your battery to reset the ecu. If that doesnt help then just get another IAC. If your tuning with Hondata you should be able to go in and adjust the IAC, plus you can remove you 02 sensor with hondata as well

 

change the iac ,but there not cheap

 

is there any thing else that would cause a 3k rpm idle? i dont want to replace it if its not the problem

 

Check and see if there are any plugs that should be plugged up in the ntake manifold. I would also check the IAC.

 

say i plug the hole in the throttle body that leads to the IAC. The problem persists. Which means it wouldnt be the IAC as far as my knowledge goes. Am i wrong?
