If an injector is stuck open, it will expell lots of white smoke, and will smell of raw fuel. If it is black smoke and running poorly, could be possible faulty map sensor or vacuum source to it.

Yes, replacing the two injectors would be advisable. The injectors have constant power on I believe(color) the pink wire, and are controlled with pulsed ground from the PCM. If there is two that are leaking with key on pressure, disconnect them electrically just to check. If they still leak, replace them. I don't see a need to replace them all, unless you feel that contaminated(dirty) fuel may have played a part in the cause. Otherwise, just replace the two.
