Startup Misfire

I've had a startup misfire that generally lasts a minute or two which was once occasionally and is now regular. No CEL. I just replaced the DI cassette to no avail. I began pulling injector wires as it was running and noticed cylinder three was the misfiring cylinder through this diagnosis. I pulled the rail and the #3 injector.
I bench tested the injector on a 12V supply, ran some carb cleaner through it and reinstalled. No change.
I once had a 1990 9000S that suddenly quit sending a signal to an injector, which could be tested through the injector wire and by hooking the injector up to straight 12V and running WOT, which would temporarily remedy the misfire. It was the computer in that car. Could this also be the case in this situation? The engine management is quite different.
