I got my car smogged today, and while my hydrocarbon numbers were really low, my carbon monoxide (CO) was slightly higher than the average. Can anyone tell me the significance of the levels of these numbers? I mean, if HC's are high, you're rich, and if your O2 is low your dog needs a walk.

But seriously, does anyone know?

Oh, apparently in my situation, it indicates the condition of the catalytic converter. Low CO's mean it's healthy and converting much of the CO into CO2.
