Just had the a/c recharged after replacing a host of parts. Now that thats taken care of.. i have some idling issues as well as some surging while in a 45-50mph cruise. Its like the a/c is shutting off and coming back on.. which might have to do with the possibility of too much freon added into the system causing it to shutoff and come back on.

I use a powerFC and the idle settings are setup properly, just seems to be a more mechanical thing than anything. As i've read in other posts i searched, my compression is fine so its not that issue. The car wants to come down from a nice 900rpm idle a/c off... to a 400rpm almost stalling idle. I can manually idle the car though easily.. just wanting to get these issues cleared up.

I've read that i might have to make the PFC re-learn the idle.. but how do i do this withOUT deleting my map?

 

anyone?
