Took the z in for the always awesome cali smog check and failed the nox test misserably. Whenever ive tested it in the past its passed just barely.
This time my o2 and hc were well below the max but the nox tested at 1200 with a limit of 700.
Im thinking its the cat but wanted to check what you guys thought first. I checked the egr, tries to stall when pushed up and diaphram moves when engine reved. I sea foamed the car yesterday if that could effect it.
Thanks for any help
