Engine Mechanical problem
1997 Cadillac Catera 6 cyl Two Wheel Drive Automatic 160000 miles

The check engine light came on. The dianostics test code say 02 sensor bank 1 sensor 1 and crankshaft sensor A malfunction with cylider 1 misfiring. What would cause these problems? And how would I fix it?

If the check engine light is the only symptom, I would clear the codes and see which one(s) come back.
