Hey guys.

My car keeps giving me the po 120 and po 125 code.
It looks like the fuel mix is very fat. Smells at idle.
Nothing wrong with the perfomance, the car drives like a beast..

 

Do you have a open vented BOV? With these the car run fine without performance problems but can cause the car to run really rich, But my evo9 all stock from the factory seemed really fat, It was wicked white and the back bumper even with all stock exhaust was always black from all the soot.
