Can a coil go bad from sitting?
Can a coil go bad from sitting?
12 volts would kill them in short order but even at 7 they are becoming damaged every time the coil fires. It may seem odd to lead off with a short tutorial like that but when a car sits, that arcing damage on the point faces start to corrode. When the corrosion builds up the gap closes and the car won’t run.
What happens when the ignition coil fails on a Dodge Dakota?
On Dakotas that have a distributorless ignition system, a single coil is used to fire two spark plugs. When one of these coils fails, the result is a steady miss on the related cylinders, rough running, and reduced performance. If testing reveals two dead cylinders connected to the same coil, then that coil is faulty.
What kind of ignition system does Dodge Dakota use?
