Yo PCB, don't digress yet!
After driving around today, believe it or not, P0171 came back on (after I drove it hard for a somewhat extended period of time--was in a cruise). Only thing is, my STFT stayed where it should the whole time and never jumped above 10% or so. It appeared that my LTFT was bouncing from 2.3 to 25%, so clearly some issue is still afoot. When I was done driving hard and gently drove the thing home, no codes came on, and I had nominal levels.
Looks like my fueling system is indeed part of the problem!
