Weird thing is when I start it in the morning (before any of this happened) no belt squeak, but when I would start it in the evening after work the belts would squeal...every day, both belts are tight and are new Napa units, a/c bearing is new as well.

Also today on the way to the parts store after work it did it again with the a/c on, (stumbled, engine light came on and wouldn't idle) so I turned it off, restarted car, light went off and car idled fine again. I then continued my trip with the a/c on only at speed, when I slowed or got near idle speed I turned a/c off....idle didn't slow nor engine light lit. So Alternator bearings maybe or idle up solenoid (does it have one?)
