So i just took the newly built engine for a smog and failed horribly on NOx again. With the old engine it became a routine, change plugs, wires, cap, rotor, o2 sensor....take test, fail with High NOx, buy a cat, pass smog.
This time, since I got tired of paying for retests, bought the cat first. Still failed with high NOx and this is on a newly rebuilt engine.
This happened once before with a honda about 3 years ago. I bought a discount cat only to find it was a 2 stage, not 3 stage cat, and again failed with high NOx. Bought a cat from NAPA and passed.
So I'm looking at this MagnaFlow Catalytic Converter 39221, and on the box it says, "MEETS CARB CALIFORNIA AIR RESOURCES BOARD EMISSIONS REQUIREMENTS AND CRITERIA OF FEB. 15 1989" Didn't CA pass new emissions regulations requirements recently (like the last 5 years)? And could I just have the wrong Cat?
