I have changed the spark plugs and the air.
1999 CHRYSLER 300
I have changed the spark plugs and the air filter. What more can I do to increase gas mileage

Change all the oxygen sensors as they determine how much gas is sent into the engine. Old oxygenb sensors can make a car run rich and therefore not get as good a gas mileage.
