Just out of curiousity, do you drive around with the air conditioner on all summer? I rarely ever use it, but the two times I have something horrid has happened, and the engine always seems to lag and sound a little funny when its on. It's probably a total coincidence that the 2 times in 3 1/2 years that I've had problems were a day after running the air, but just wondering if anybody else has noticed the GTO doesn't seem to be very fond of air conditioning?
I rarely use it as well. But for what its worth, everything seems fine when i put mine on. I come from a family of small 4-bangers, and if you want to go uphill, you take the AC off... Kinda' just turns into habit after a while. I learned to enjoy the summer air, even if it is filled with noxious crap.
Yea, I definitely don't need it and prefer the windows down. The last time I ran it, I didn't know the water pump wasn't working right, so it was probably overheating anyway and running the air was probably just the tipping point that made the problem really obvious. I guess its probably just better to keep it off.
I live in Southern California in an area where it tops 100 degrees in the summer. I use my A/C when necessary and haven't experienced any problems using it. Sure it uses some of the cars power, all A/C systems do but with the kind of power these cars have it's really not that bad.

I'm down in the Houston area of Texas, we got 90% humidity and 100+ degree heat. i use my a/c all the time. i have noticed that when i give it the gas without down shifting, the a/c compressor shuts down momenterly, but the fan stays on. this results in humid air coming into the car for a few secs, but it goes away as soon as i resume driving normaly.
i've had other cars that have done this too, so i'm if there is a power loss, its when your not demanding much power anyways. could be vacumn acuated or somthing
