My truck isn't getting the mileage it did when it was newer (13 vs. 16). It has the 3 valve 5.4 engine - 1/2 ton, 4wd, 3.54 axle, automatic, extended cab, 6.5' bed. It's time to change plugs, will that do the trick or do I need to clean the injectors? Will a gas additive work for cleaning the injectors?
