Rough Running - Coil Problem?
The car has been running rough and I wasn't sure what the problem was. Tonight I have a better idea. After coming back from the store, it was running rough so I popped the hood and I could see a spark arcing from the ignition coil module to the block. :eek: It was doing it pretty regularly.
Is it the coil, coil module, or something else? How ugly of a fix is this? I am a novice but driving around in the backup Escort is motivating a quick fix. Thanks guys!

Not a bad job, have to undo two nuts/bolt studs on the coil bracket, and another stud on the power steering fluid resevoir bracket down below, then slip the coil unit out (have to work it past the wire harness and plug wires) ~20-30 min.
If it's the first coil put on the car, you have to drill out some rivets that hold the coil on, pretty easy, then replace the rivets with supplied bolt and nut. ~20 minutes.
Then replace unit back on car ~30 minutes.
Depending on car mileage you should probably replace the coil module, and coil wire (I wrapped my coil wire in 3/8 fuel line - fit it like a glove, instead of the plastic loom) Probably looking at close to $100 if you replace, coil, module and wire.

While your up to it....check your spark plug gap.....this can cause problems enough to pull your hair out...
