Anyone running a powerfc on 93rx7 close to brevard fl
 

For some reason my idle will bounce with the ac on only. With idle and headlights on it works as it's supposed too... Any ideas? I would like to compare and contrast if possible

Here's the email for a friend of mine that tunes my rx7 with PFC. He's just outside of Daytona.

If he doesn't reply fast enough, let me know and I can give him a call. He tunes Hondas and Evos as well when he's in my neck of the woods, but RX7s is where his heart is.

IIRC this is a long standing issues with either a ground or a resistor involving the PFC and AC. If you check out the PFC section of the site and search for AC issues you may find info relevant to your situation. Good luck!

I did but they all relate to either dial position (1,2,3 or 4) giving humid not cool air. None relate to idle

I emailed him 5 min ago thanx

Everything is fixed!!! All I had to do was follow the directions.... 10 min idle (without any loads) 10 min with defroster on and 10 minutes with a/c on and defroster off. It literarily took 7 to 8 minutes before the surge stopped! Let it idled for 5 minutes more then turned the car off waited 1 minute and started it again and the surge was gone"!!! So if your idle is bouncing or hunting or surging with the air conditioning on but works on all other settings all you have to do is wait... It sounds easy but all of us who had or have this problem do not like to hear the engine for crazy for longer than 1 minute or two but I was fed up and waiting a few minutes longer fixed it""""""!!,!!,!
