Under Texas law, I’m subjected to my states full emissions test for state inspection. Unfortunately my car repeatedly fails the NOx portion of the test. I have replaced the catalytic convertor, EGR valve, spark plugs and ran a number of emission lowering fuel treatments. Would replacing the 02 sensor help my problem?

The technition had to tell you why its not passing the test, they wont fix it but let you know what to do if not he is a bad tech. But yes the oxygen sensor would be a good idea and air filter fuel filter pcv valve. In the past I have used techs who pass me under the table im sure theres some around in ur area just in case it cant pas.
