Q: I own a 2001 Z28 Camaro and in June of last year I had the same problem -- the check engine light came on and I had to replace an oxygen sensor. My check engine light is on again so I took the car to the dealer and they told me it was the oxygen sensor and air pump, which cost $814.00 to replace. With 67,000 miles is it worth it to fix again? I didn't have this problem the past six years, now its every year.
A: The air pump keeps fresh air flowing to the exhaust system, this is critical to the catalytic converters because without this fresh airflow, the "cats" will overheat, resulting in internal clogging and burning of catalyst baffles. Plus, when you leave a faulty O2 sensor in the engine, it causes fuel delivery malfunction. Finally, if your state has emissions laws, you won't pass state emissions inspection. I recommend you get it fixed.
