Re: setting idle speed (6spd)
yes, the IAC count needs to be around 50 with the AC off. using the software, turn the idle screw on the throttle body clockwise to increase idle so that the iac reads 50 or so. It has to be enough for the pcm to keep the set idle rpm in the program. too much, and the idle will be too high. too low and youll see the motor wants to stall when the ac is turned on.
