I got a CEL, so I used the logging software EvoScan to check the codes.
Evoscan gave me quite the list, but I don't think it is accurate.



The car runs perfectly fine, except poor gas mileage. I assume it was just my O2 sensor, especially since my A/F Gauge is not blinking back and forth and stuck at lean.

So, I am wondering if they share a certain code and evoscan is just reporting all the things that might fall under that error code?
