Running rich doesn't have as many causes I think. The only other things I can think of off the top of my head is a very bad O2 sensor, which can be unplugged to confirm. The DME will run just fine without it. It could also be a failed coolant temp sensor, intake air temp sensor, or failed wiring pertaining to either. It could also be leaking or stuck open fuel injectors. You can pull the fuel rail leaving the injectors still attached, held over a catch pan, and crank the engine to look for a fine, even, pulsing spray pattern (with the ignition coil primary (supply) disconnected first). When you stop cranking, look for fuel pressure bleeding off by leaking out the injector tips. The rail should hold pressure after the engine stops. Besides fuel pressure, most anything else wrong would lean it out.

Ok! Finally got my new FPD... pricy S.o.B they are, 95$ for this thing, gosh!
Anyway, I put it on annnnnnd
YouTube - Stalling
Well, the smoking stopped thankfully but it still stalls D: I recall you saying something about coolant temp sensor. If that indeed has gone bad, how would that affect my mixture performance? And is there a way to test the temp sensor to ensure it is bad?
As for injectors, I bought re-manufactured ones recently so I'm HOPING it isn't them otherwise that guy will be hearing back from me and experiencing my irritable side lol
The other half of the video
YouTube - Stalling pt.2
I had the o2 sensor out the entire time I was trying to test as you could probably hear. I've done the 'ear to afm' test and it doesn't sound like its scrapping so I'm assuming my afm is indeed good. What about my TPS? If that were bad, would that cause it to stall too if I try to give it a tap?
