Switch the spark plug wires around (1 and 3 with 2 and 4) and see if the firing and or non firing follows the plug wires. If yes, then the spark plugs, plug wires or spark plug boots are probably bad.
If it is a two coil system... there is not two coils in each package.... there is only two ends to the same coil and a spark plug connected to those ends.
If the coil on 2 and 3 was bad, 2 and 3 would not fire.
If the coil on 1 and 4 was bad, 1 and 4 would not fire.... etc.
That is not what you are seeing so I would first suspect what is in between the coil and the spark plugs, including the spark plugs.

If the wires are the replaceable type, Inspect the ends both at the coils and the plug caps. Could be corroded and you can cut 1/4" off, screw them back in and run it.

Disconnect them and look at them. If you see any green SHT or black burnt, trim the ends and put them back on.
