COP testing
im supposing my dead cyl 4 is due to a bad coil on that cyl, but i need some test procedures, ohms specs, voltage drops, things of that nature, also some fuel injector specs would be nice as i havent totally ruled out a bad injector yet
im not one for just throwing parts at a car, therefore any help would be greatly appreciated. |

Start the car. It'll run rough. Go around and unplug each injector. If it gets worse, that coil pack is good. If it stays the same, that cylander is not firing, so it's either that injector or that coil pack or that spark plug.

If you swap the coil for its opposite number on the other bank, and the one not firing moves to the other side, then you know it is a duff coil Joe
