Re: Added A/C and now idle is too low/rough
Factory style, you would let the PCM control the compressor. It takes a little wiring, but isn't too complicated. Basically, the 12v signal currently going to the compressor clutch goes to the PCM instead and then the PCM triggers a relay to turn on the compressor.
You can add the refrigerant pressure sensor if you also want the PCM to run electric fans, but it's not needed for the idle speed adjustment.
*edit* Or just bump it to 700 like Jason Banks is doing.
