Question Driver side cylinder bank not firing after new plugs/wires. Still sparks at coils.

First Post! woot!
At any rate, I'm working on my 96 Ranger AT w/ 179K miles. I just picked it up as a light duty truck a few weeks back.
Ok, so here's the situation:
Truck ran smooth and OK, but was hesitant to go over 2.8Kish. Still smooth, but felt like it was very lacking in power.
Changed the plugs [NGK Plats] and wires (which I think were both original equipment!!!) Over half of them didn't have electrodes left above the porcelain. And the wires were nearly impossible to get off. I actually had to cut the rubber plug shields with razors because they were formed into the plug insulators.
Cleaned Throttle Body.
Also dropped the tranny pan and changed the fluid/filter.

Now the problem:
Runs like straight crap. Misfires like crazy, and the engine kicks like a mule.
I can remove ANY ONE of the passenger side wires from the ignition coil, and you hear the motor die down.
I can simultaneously remove TWO wires from the driver's side bank, with NO difference in idle. (probably can remove 3, I just havent tried cus I kept getting shocked.)
They are still sparking, because as I remove them from their sockets, I can see and hear the sparks jumping over to the wires.
No shorts in the wires and they dont contact anything they could ground out to.
I have checked for any vacuum lines I may have knocked loose, but this would have no effect on why a whole cylinder bank isn't firing.


Anyone ever hear of something like this? Please help me out
Thanks

I would say you have the wires crossed. Clean off the top of the coil near the plug towers there are numbers marked on it for what plug goes where. Its easy to get them reversed, I have done it.

Thanks, I thought the same thing at work. IDK if someone will reply by morning, but I assumed it to be like the passenger side. Does each cylinder attach to it's respective position? E.G. "Front to back"

will check it out in the morning. too cold right now.

need to heat the room up playin some games

Yeah its a little confusing, the passenger side is in order and the drivers side is not. That top picture is not correct, the second one is. Go by the numbers on your coil and it will run right.
