i have a problem with my sonoma gt it only has an k&n airfilter and a catback. ok this is what happened i havent driven it in about a week my buddy came over left his lights on in his car and his battery died so i decided to jump him with the truck since it has an optima. i jumped him he left then i shut the truck off for about another week. i started it it idled fine for about 10 mins i was letting it warm up then i herld a sqeiling sound got in it put it in drive and it felt like it just died. it hardly idles it sounds like it has a huge cam like maybe it lost a couple cylinders so i sprayed each cylinders maniflod with water and there wasnt much difference between them. i have to brake torqeit at any stop signs or else it will die or come close to it.any help will be really appreciated thanks :tup:

Take tension off the serpetine belt and see if the pulley on the alternator spins freely or not. Bearing in the alternator made have seized up. That may have been what made the squealing sound.
