Ok everything passed but two areas, my THC was 2.6 needs to be 1.2 or less, and my NOX was 5.4 max 3.0. Give me ideas of things I can fix easily I have all weekend to work on it, reasonably car saavy but need some guidance. Thanks.

 

Basically if you have high hydrocarbon then you are basically running too rich. I would do a basic tune up. Change the plugs, distributer cap, and rotor then check timing. Hopefully once you lean it out then you NOx levels should decrease too. Next time you test, get your cat as hot as possible immediately before testing. Hopefully your cat will work efficiently enough to help lower HC levels.
