Barely passed smog - high HC advise
Kindof amazing, at the exact limit on the two numbers.
From what I read its unburned fuel, any advise based on the other numbers the most probably cause?
It does smell gassy and the mileage sucks (~11mpg). Otherwise it seems to run fine.

Sometimes it's arcing inside the cap, replace the cap and rotor.

Check your fuel pressure and tps setting.
Your % co2 should be closer to 15.1
