Sounds like a spark plug wire is loose. Prolly #6 
Car died, No scanmaster reading, No start

LOL! Don't give up! Did you check all your spark plug wires? Make sure they are pushed on the plugs tight. Check em on the coil too. 
I checked all of the plug wires, starting with #6 I am starting to think it isn't an actual miss, just a really rough idle. The engine kinda lopes. It rocks the whole car and bounces the gas pedal. It revs quickly in park but falls on it's face under a load. I honestly don't know where to even look next.

Can you swap out your MAF with a known good one? I had some really odd symptoms when mine went bad. Worth a shot.

How did it run before this? How did you repair the wire/terminal problem?

I would do a tune up, but could be another broken wire some were else. If you do not want to mess with it look for a garage that speicalizes in auto wire repair and have them poke at to find the issue. When it comes to that i let someone certified in it take care of it. good luck.
It was running great before. It might have been a little rich, but it idled great and pulled hard.
Haha, I just picked up some spark plugs on the way home. I am going to go ahead and do a tune up and see if it helps. Good idea about the specialty shop, thanks.
I just cut off about an inch of wire after the break, stripped it, put a new connecter on it and put it back on the battery terminal.
I changed out plugs last night and all of them looked the same except number 5. It had fuel on it. My question is should I be looking at the ignition module or coil pack? I already tried swapping out a new wire it it didn't change anything.
I have attached a photo. All the plugs looked like the one on the left except number 5. Number 5 is the plug on the right in the photo.

I just pulled plug wires one at a time with the engine running. There was a change in engine rpm on all of them except 5. However, when I cranked on it with the plug wire and plug out against the valve cover it appeared to have good spark. Maybe it is just not enough spark? Any thoughts?

That is about normal for the plugs. It was probably fouled due to just running on alky alone. If stumble has persisted then it is a wireing issue. Locate a shop for auto wire repair and give a few days at it and see what they find.

If it's a miss on cylinder 5 might have wiped a lobe off the cam not allowing the valves to open (assuming the valve spring is not broken) or could be collapsed lifter. Pull off valve cover and take a peak
After I pulled the plugs and found fuel on #5, I tested the spark. It looked good so I started looking for other possibilities. I hooked up my fuel pressure gauge and it showed good pressure at idle. I shut it down and looked at a few other things, maybe 3 minutes elapsed. I looked back over at the fuel pressure gauge and it had lost almost ten lbs of pressure in that 3 minutes. My thought was that possibly the fuel injector was staying open and dumping fuel constantly. It also would explain the rich condition, rough idle, and fuel fouled spark plug. I unplugged the #5 injector and the idle smoothed out considerably. It still has a miss, but it is not anywhere as severe as it was before I unplugged the injector.
Any thoughts about whether this is possible or am I way off here?

I'm thinking that the injector was dumping so much fuel that even the good spark at the number 5 plug that I got when testing, wasn't enough to cause combustion in that cylinder. That would explain why there was no change in rpm when I pulled the wire to that cylinder.
I don't know, I could be way off. I have spent a lot of hours working on this car over the past week. I'm may be starting to lose it
