The ignition ayatem works on the wasted spark principle whereby the plug sparks at the top of every cycle. If one coil fails then it very likey its partner will have have problems also. The coils are wired 1-4 and 2-3.
Try disconnecting each injector in turn and see which cylinder/s are least affected.
