Think I've got it figured out. I fired it up this morning before heading to the parts house. Popped the hood and was examining the di computer. All bolts were tightly fastened. I decided to give the plugs around it a nice jiggle, and Lo and behold as soon as I jiggled the connector in the attached image there was an auditory difference in how it was running, instantly sounded much smoother.
After this I went and grabbed maf cleaner and some carb cleaner for checking vacuum leaks, and while doing so I noticed the issue was much improved. Still a little flat, but definitely better. When I got back
I did a datalog of it in this state.
I let it cool down for several hours, then went back out to check for vacuum leaks, all good on that front. I then unplugged the previously mentioned connector, checking the pins, all good, plugged it back in firmly. It's at this point that I disconnected the battery to reset ecu. After re-connecting I let idle for a few minutes, then went on a test run up and down the street. Bingo. She's back!
I then did another datalog of this state
Now as you've probably guessed, I don't know what I'm looking at in these graphs. Like I know what the values represent, but I don't know what they should be in relation to each other. It was mentioned that at WOT my afr should be in the high 11s? I see the afr still in the 12s, but the command afr eventually gets into the high 11s. I'm guessing command afr is the value the ecu is attempting to reach, and afr is the actual value?
With all that being said, does the last log I posted seem good or does it indicate that I may still have something going on (even though the issue which lead me to create this thread seems to be resolved)? Still haven't cleaned the maf, but I didn't want to do that quite yet (introducing more variables into the equation and what not).
