If the ignition coil is bad, you cshould be able to identify it when the engine is running by removing and reinstalling the wires one at a time. You should notice that if there is one dead cylinder there should be a second, as each pack controls 2 cylinders. If you can identify this to be the problem, then you can probably skip the rest of the stuff. If it doesn't seem to be the problem, you might need to change the icm. I don't see where the wires and plugs would be at fault if you just replaced them, unless you either bought the wrong ones or you got some with inferior quality. Most wires are OEM size or larger so resistance shouldn't be a problem. Reguardless, $850 is a bit extreme for a job you can do yourself for about half the price or less.Often you can get a decent one at the junknyard for pennies on the dollar.
