Scan engine and see what cylinder is misfiring then swap the coil out of the missfiring cylinder into the next one and put that coil into the original missfiring one. Delete codes and the start engine, rescan if it's the same cylinder it's not the coil, if it's changed to the other cylinder then it's the coil.
