Well my girl took her car to get inspected and they told us that the Nox level was too high. the standard for low speed is 829 but it was putting out 1466. at high speed the standard is 751 but it was putting out 1266. so the car fails the Nox test. do y'all know what could be wrong and how much to fix it? thanks guys.
