The coil is 3 coils with 2 outputs each. Usually only one side of the coil shorts. I like to take the wire of the missing cylinder and switch it with the wire strait across the coil as they fire together. I watch live missfire data, but you could switch wires, clear codes, then see which missfire code comes back. If the misfire moves to the switched wire cylinder the coil is dirt. If it stays the same missfire code its that plug, wire, injector, or compression. Sounds kind of stupid but it works. Coils fail alot esp. on cars were there in the rear taking alot of heat over a manifold.
