I need help my recently rebuilt 190e 2.6 failed Calif smog miserably. The hydocarbons were 3x max and the Nox was pretty high, both dropped in the speed portion but were still too high. I need direction; i am pretty fair amateur. I am thinking the cat are due to be replaced (there appear to be 2 of them and the back doesn't appear to be replaced in years. Or thinking about this all wronf and should looking at a sensor such as the air mass sensor. I don't mind repairing but i don't want to be throwing money for no reason either Any help would be appreciated. Thanks, Jim
