Is it really getting bad fuel mileage or just seems like it? First do a series of mileage tests. Fill the tank by letting the automatic fuel shut off stop the flow. Then slowly add more fuel until it shuts off the second time. Note the mileage. Drive 100 miles and refuel the tank the same way. See how many gallons used and divide that into miles driven. Record results and do the test again. Com-pare results to see the mileage average. If it is low, check for fuel leaks. Check the plugs for wear. Check the fuel and air filters. Scan the engine computer to see if there are any drive ability codes.
