I think you are right. I was looking up the infamous GM belt squeel and it sounds dead on for what it probably is. I didn't hear the squeel initially on start ups before going to the exhaust shop. But of coarse I had open exhaust. When I got to the exhaust shop and turned the truck off I spewed radiator fluid everywhere (I forgot to tighten the a heater hose
). I cleaned it up pretty good, but I'm thinking that the radiator fluid is still on some things. I sprayed belt dressing aon the hose and it made it 10 times worse. I then sprayed some carb cleaner on it and it stopped while I was spraying it on the belt. As soon as I stopped spraying it the squeel came back. I'm going to take the belt off and clean it and the pulleys really well.
As for the crappy brakes all of the sudden and the high idle, I don't know. I'll have them check the tune when I get the new computer.
