I think I have to replace th ignition coil in the Ranger.
my question is are there better ignition coils out there that help with gas milage, since I am replacing already.
issues I am seeing are missfiring, and poor gas milage, replaced the plugs last wekend check engine light light went away for a week, the spark plug cables are only about a year old. a couple of weeks ago had a hard time starting the truck, and had to jump it, the battery is good, I just kept trying to start it because it sounded like it wanted to start.
