I have a 1992 Oldsmobile Cutlass Supreme S. It has the 3.1 MPFI, 150k on it. It has lately been making a loud whirring noise under the engine over by the drive belt, and when I hit the brakes to a complete stop, it idles very rough, and randomly tends to stall (die). It sometimes backfires really loud after driving a while. I've heard three different things, it could be the steering belt, timing, or alternator. HELP!
