Do you have an engine miss through out your driving range? It is possible that your spark plug boots and springs are in. need of replacement. The 4.6 L engines with coil on plugs are bad about the boots and springs fouling up, your car will intermitently act as if an injector is not firing because of this. Many people end up replacing the entire injector when indeed it is only a $5 problem instead of $50.
