When driving back to college my O2 Sensor light came up on my dash. I know that it controls the balance between the oxygen and fuel that goes into my engine which could cause my car to run rich or lean which will cause my MPG to suffer till I get it fixed but I was wondering if there are any other affects of a faulty O2 sensor. Thanks guys.
