Are you getting DTC P0300? the random misfire, or are you getting one of the P0301-P0304 codes? Fuel injectors are only one of the explanations for the latter bunch, and the P0300 is not a injector code.

EDIT: Also... have you checked wires to the ECM/PCM for an open? The Honda FSM indicates replacing the ECM/PCM if the injector is not the fault and if there is no open between the injector and the ECM/PCM.
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
