My 98 GTP with a reprogrammed ecu from 3800performance.com began running really rough yesterday in the extreme heat. I was caught in a traffic jam and every time I would run my A/C the water temp would slowly climb to about 240 and then the car would begin to shake and idle poorly.
It basically felt like a bad miss. I'd turn off the A/C the water temp would come down and it would idle correctly again. Has anyone ever experienced this before?

sounds like your AC compressor is putting more of a load on the motor than it should or your fans aren't functioning 100%. Most likely the AC compressor is causing you some issues.

The odd thing is it wouldn't go away when I turned the ac off it would only stop once the temp fell down to say 225 or so

There is programmin in place to limp the motor on less cylinders etc when it's too hot.

Ok that makes sense cause that's exactly what it felt like

You may want to consider doing a flush of the cooling system. Sounds like you are not cooling to car properly.
