I recently failed inspection for emissions NO2. I had changed the oil, spark plugs and wires before I went. The car idles petty smoothly. Going to change the gas filter next. Could the NO2 be the oxygen sensor? If it is could you tell me where it would be located.
This is for a 1997 chevy cavalier automatic 97,000 miles 4 cyl I couldnt find the engine size and I dont have a manual. Thank You
have the same problem?
