I installed some bolt ons and a new tune with my XCAL2 about a month ago. I set the TPS voltage with my volt meter to 0.98V like your supposed to. It took only a day for the computer to learn how to idle normal. I thought all was good.
Well, today was the first day since last fall that i actually needed the AC on. I clicked it on and the car got all confused with the idle. It idles fine at 700-800 rpm at a stop, but as soon as i hear the click for the AC condensor kick on, the idles pop up to 1200. Once it clicks off, then it comes back down. Also, the idle hangs at 1500 RPM pretty badly with the AC on until i come to a FULL stop and then after a couple seconds at a full stop it goes down.
Does the computer have to learn the A/C idle seperately? Is this normal and will it go away as soon as it learns the idle for the A/C in a few days? I guess i just assumed that as long as it learns to idle properly, that it will do it with our without the A/C perfectly.
