Easiest way to see which plugs are firing is to run it a bit, then see which ones are hot. If it’s running on only two cylinders, it’s likely either the top two or the bottom two.
If you decide to check the coils, remember that you have to test across the two top plug wires to test that coil, then across the two bottom plug wires to test the other one.
