1997 C1500 Vortec 350 Question
my dealership just traded for a truck im thinking about buying. it has to have a little gas or starting fluid sprayed in it to start, and after that it will run, but blows smoke out the tail pipe. smoke smells like fuel, not coolant so im thinking its not a head gasket. guy who traded it said it was an 02 sensor, and i have yet to pull the codes on it. Any ideas? Im thinking if it is an 02 thats making it run rich that may be why its hard to start along with a possibly clogged fuel filter.
