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:
