Hey all. Been a busy week, but who hasn’t had those lately? I had the code read and it came up P0171. Mass air
Flow sensor. Subaru #22680AA380 197400-511. Denso. The Subaru part is about $150-175. Auto zone had their replacement versions at $125ish. Anyone used anything they can recommend? Or ones to stay away from? See knock offs from $20-45. What’s everyone using? Thanks. Ron.
