Fuel Saving Tips
Did that yellow or red Check engine light come on? Have it diagnosed right away and don't ever delay if it needs a repair to your Oxygen Sensors and Mass-air flow sensors when they go bad. It will cost you a lot of money as they reduce MPG or may damage the engine if they are not functional and kept properly adjusted.
