Faulty oxygen sensors often lead to faulty cat. Converters. The coverters should last lifetime of vehicle so when they fail there is normally a problem elsewhere causing it to fail. Yes you can drive with a bad cat. Coverter but it may affect fuel mileage and you can't pass smog tests if your state requires them.
