It use to get good mileage.It has 130,000 Miles and runs great. I do the oil change, clean air filter, changed spark plugs and wires, also keep tires pressure good but my gas mileage is still going down what can I do to make it higher again?
 
Clean the throttle body and MAF sensor will help you keep your gas mileage at it's optimum. Good luck and hope this helps you.
