So, I had the pleasure of doing one of our fun bi-annual smog tests here in the Golden State. I passed (original cat) but upon looking at the numbers it appears I've got something going wrong.

All of the test measurements produced numbers pretty far below the max and and below average...except for 1. On the hydrocarbon measurement at 15MPH I was exactly at the max and for the 25MPH I was close. I also noticed that my oxygen measurements for both of those were 0.0%. As much as I'd like to believe my engine is running perfectly efficient, consuming every oxygen molecule, I don't think that's right.

I'm thinking either my oxygen sensor is done or my AFM needs to be "retracked." Anybody with a BTDT story here?
