Hey guys I'm new to this site. I own a 94 r32 gtr and I have some issues with the idle. It constantly idles at about 1300rpm, when cold and when at NOT.
I've taken the aac valve off and cleaned it real good with the throttle body cleaner and found the internal spring was sticky. After cleaning the aac, the spring moves nice and easy. Reinstalled the aac with a new gasket and adjusted the screw but it couldnt go in any further and idle was still no different.
I then installed an apexi power fc and adjusted f/c idle down to 1050 and it started to hunt.
It's as if the automatic choke (if rb26's have them) is stuck on all the time..
