Hey im new to the mustang scene. My car (listed in sig) get between 140-170 miles per tank of gas. I dont have a check engine light so i dont think that its o2 sensors. also i can smell that the car is running rich. other than that can you guys think of any other things that can be causing the car to suck down gas this badly. BTW im not driving it hard. sorry if this has been posted before and thanks for the help
