You'll need to check voltages with INPA. Although I'm fairly certain they will throw a code when they go bad if the voltage swings out of range. I've been dealing with a similar misfire as soon as the car uses readings from the oxygen sensors, I'll feel a few misfires (no codes).
These injectors fail by leaking down, but can also be partially clogged and just not flow properly. I've also checked for leaking injectors, but mine are fine. I am contemplating swapping the upstream oxygen sensors from bank 1 to bank 2 and see if the issue moves (my STFT on bank 1 are very high), or swapping one injector at a time from bank 1 to 2.
