    You need to scan the computer for codes. A 1993 Pontiac has a pretty good computer system for diagnostics and there should be a code or 2. Have a good tech scan it and than tell you what the codes mean. You probably get a Check Engine Light on at times, yes? Other wise you can guess and replace parts ( expensive ) for weeks and not solve the root cause of the problem.
