That is possible if the altenaotr is dropping out, no codes? If you disconnect the egr valve vacuum suply and plug it off does it still hesistate? At what speed is the hesisiation, take off from a stop or highway speeds? Feel like you are driving over a washboard road?
Ok yes it will run off the battery until it depletes the battery reserve power so need to adress any charging system concern first. Try unpluggint the egr valve and see if the concern continues. Certain model year applications had egr runner ports in the intake manifold if the egr valve is mounted to the side of the lower intake manifold. These ports would clog up and cause random misfire concerns when the egr valve is commanded on. So removing the egr vacuum supply would disable the valve operation to test if this is an issue
Hello, coils are a common failure but they wont let you put it on before buying it, I have seen a lot of issues using aftermarket coils so I would recommend sending the money on a ford coil which will come with a 2 year unlimited mile warranty if it fails again own the road
