Re: CEL question
If you haven't driven the car, then you don't know that it runs fine. All of the O2 codes you have there are related to the primary O2 sensor, not the cat or secondary O2 sensor. Do you have the OEM exhaust manifold, or aftermarket? If you know there's an exhaust leak, why don't you fix it?
