if they are still using delcotronic distributors, would suspect a worn distributer-
I'm thinking crank or cam angle sensor if either are bad it would run very rough or not at all. not to mention it also won't show misfire codes if either is bad or poss loose, full of debris . OBD II RESEARCH SENSORS TO SEE IF YOU HAVE THEM ON A 2K MODEL.
