Engine Performance problem
1998 Oldsmobile Aurora V8 Front Wheel Drive Automatic 113000 miles

Our Aurora has just begun to miss. I wonder if it's bad gas, plugs, or the gas cap. The check engine light has been on for a few weeks. The rough running has just begun within a few days. Engine had been running very strong. This miss is a reaL SURPRISW. Suggestions? Thanks

You need a tune up. If you look at the ignition coils at the rear of the engine and remove the plug wires one at a time and put them back on you will most likely find a coil tower that is rusty. Replace the plugs and wires and also replace each coil that is rusty. Hope this helps
