Injector pulse too fast/long on cylinder number 1 all other injectors have what seems to be normal pulse time. Number 1 cylinder loads cylinder with excessive fuel due to excessive "on" time

Switch coils with another cylinder to see if it goes there. If it does, you have a bad coil. If it does not, check the wiring back to the pcm. If that is good, you my have a failed pcm

What would the ignition coils have to do with injector pulse width? Pretty sure nothing ! Is there any type of resistor in injector wiring on the harness that leads back to the pcm. This car runs just has the issue with injector pulse width on injector /cylinder 1
