This code means the pcm sees an open circuit or no injector response when the pcm signals the injector to actuate. Check the resistance on the injector and compare it with another nearby. The running poorly is a misfire due to the injector a not acutating or b stuck open in which case it would run rich. Install a noid light on the injector connector and verify that the pcm is capable of controlling the injector.
