Coil: Electrical device that creates the sparks that can be seen in spark plugs.

It is a high-current generator. The engine's computer sends a signal to the coil so that it can boost the energy that will be conducted through some special wires to the spark plugs and, in one of its ends, the spark that will later spark the fuel mixture inside of the cylinders will be generated.
Was driving fine then died. Keeps throwing a code for misfire in cylinder #6. When started back up sounds like it has a blown motor. Have replace all spark plugs, coils, valve cover gasket, oil change. Please help
