I own a 2004 chevy silverado 1500 with a 5.3 liter eng. Recently the eng light came on and it started running really rough like it was going to die. It not only runs rough at idle but also in gear or hesitates when I excelerate from a stop. Ive done countless diagnostics, only to come up with multiple problems it could be. One was a possible blown intake gasket which I replaced and the truck ran fine for a little bit then the eng light came on and started the same thing. I also bought the 2 before cat oxygen sensors but havent installed the yet. Can anyone tell me what to look for or try from here?
