On this episode I go through the diagnosis of a 2015 Infiniti Q50, 3.7L V6, with a P0171 and P0174, lean condition. I'll share my thought process through the diagnostic steps tracking down the source of the positive fuel trims. My goal on this show is to share vehicle diagnostics that challenge me to come to a precise conclusion, this vehicle being one. I have a gut feeling I know the solution, but not enough data to condemn a part.
