Final Approach
It's not a 5/6 cylinder issue - it's that with a clogged injector, the fuel pump is delivering the same amount of fuel, but forced through 5 injector lines rather than 6. Makes the other 5 cylinders run way rich, hence the black smoke. This reduces power way beyond theoretically running normally on 5 cylinders.
You're correct, I know better. D'oh. I was picturing a more modern injection system in my head for some reason when I made that comment. And I don't know why I didn't pick up on the black smoke either. One cylinder running super lean while the others are running normally wouldn't produce a bunch of black smoke.
