My 2012 Outback is blowing a P0171 during idling (I'll drive for 15-20 minutes, then when I park and let it idle for a few minutes, the P0171 shows up).

I used my scan tool to see that the MAF is reporting 0.255 g/s when idling. Alldata tells me that it should be more like 2.5 - 5 g/s. So I took the MAF out and tested it according to the Alldata instructions, and it read about 0.8v when just resting there, and then when I blow into it, it reads about 2.8v.

Are those normal voltages?

(I also tested the resistance of the Air Intake Temp sensor, and that seems to be fine).

Any advice is appreciated. Thanks!
