"It doesn't seem to be firing"(#4)
Do you mean not making as much power instead?
It's not clear why you suspect this cylinder?
Firing can be easily checked. So if it's not firing, as you say, it's an ignition issue that needs fixed and is not puzzling. {I like to take the conductance type timing light and put on the affected wire and check the pattern of light flashes. Or you need an analyzer.}
If ignition is good, checks to spec, then it's something else.
There's alot of reasons beyond that, so you need a methodical approach.
