Hey All!

My check engine light goes on and off lately. Had Auto Zone check it when on and got the dreaded P04320 and P0320 codes. Last week it went off and I had it inspected (passed) and today it came back on.

My car has 220k on it and runs like a champ. Gas mileage and power never change - always consistent. Any long term effects of driving another year or so until I get a new GS?

I hate to start going to the dealer and replacing O2 sensors and cat convertors on a car worth $3k.

Any thoughts?

Thanks.
