2006 Pontiac Montana v6 3.5l P0171 P0101 Part 2

Customer brought in his 2006 Pontiac Montana 3.5l few weeks ago after having his oxygen sensor replaced for a lean code. We diagnosed a bad MAF sensor. Fuel trims were still not perfect so I had him drive it and see what happens. Today he said the light came back on for a lean code. Let's see what it could be.
