My 2000 Blazer acts as if it "misses" a little, too, when I run the A/C. It runs just fine if I shut it off.

While we haven't had really hot weather here were I am forced to run my air conditionaire on max, I am hoping the issue is fixed. We had to replace the fuel pump a while back, and I am just wondering if that was causing my issues. Keep in mind this ONLY happens when the weather is in the 90's and I have the air on MAX. Disconnecting the battery and waiting 10 minutes clears everything up. We have been advised to replace the O2 senors but that can get expensive if you have to do that every year. The reason I thing the fuel pump might have been the culprit is my daughter has a 1999 Cavalair and always had problems with the TAC jumping and stalling for no reason. Had the engine replaced at 60,000 with the same issues. The vehicle finally would go no more after about another 60,000 or so and we ended up changing the fuel pump, and knock on wood it runs fine now. In the Balazer's case the fuel pump just up and quit in my daughters case it never quit just kept jerking and stalling a lot. Will keep everyone in formed if the fuel pump fixes my problem as well.
