Cool. Can I meet you somewhere on saturday in the afternoon?
my guess is rear 02 sensor.
I had APR take a look at my car for me. Primary o2 sensor in bank 1, coolant temperature sensor. booking time at inline soon once more 
anyone free tomorrow? i dont want to drive this thing until i find out what the cel is
Wouldnt worry about it that much. I drive ~1300 miles+ on my cel. if its not flashing you can drive the car.
