Ok, this rig is about to go on a short trip over a long hill. It has sat for 4 weeks, had to have back surgery get better and now I start it and it runs like crap, and stalls, figured it was just cause it has sat. Ran it for a little while, man it dies if I let off the gas any time, going 40 around a curb it dies (gee no power steering and no power brakes fun). I mad sure oil was ok, put in fuel additive, no luck any ideas? It ran fine before I parked it last. If it aint a Chevy don't raise it up!
