Re: Just Failed CA Smog. Now what?
I agree with Z51Jeff and Mike100. I had the NOX issue too. Everthing passed except for that on the IM240 test. I found out that I had a lazy O2 sensor on the left side by using my Mastertech 3100 to watch the voltage swing. Replaced the O2's and passed. The new results were about 40% lower. I used the Bosch ones.
