Running Too Rich.. UCF21
I took my car to get it smogged twice.. and both times I failed miserably. I had my exhuast redone awhile ago to a true dual with all three resonators deleted and the 2 catylic converters are still there as well as my stock exhaust.
I've ran some fuel system cleaner after my 1st fail, fixed some exhaust leaks, changed the spark plugs, cleaned the air filter, cleaned the throttle body and it's still a no go. The tech there said it could be a faulty O2 sensor but my car has yet to throw any codes. Anybody have any idea what it could be?
On my 1st test, i had high CO (carbon monoxide). For the 15mph test, the max was a 0.46 and I threw a 0.74. For the 25mph test, the max was a 0.43 and a threw a 1.16. Yes, those numbers are crazy..

Post a picture/scan of your smog printout please, need to see some of the other values too.
If you haven't done them recently, a new air filter, spark plugs, and ECT sensor aren't a bad or overly expensive place to start.
also, UCF20! You know this lol, i don't recall your car coming stock with air
