I agree with Blue, you should have the car scanned by a shop. If you don't want to spend the money at a shop, if your car has over 100K, and has never had the oxygen sensors replaced, that is where I'd start. BTW, your car only has 2 oxygen sensors, one in the rear exhaust manifold and one past the converter. Cheap scan tools will usually trip a "bank 1, sensor 1" and/or "bank 2, sensor 1" code even when only one pre-cat sensor exists.
