Will confirm fuel numbers as soon as possible.
Assuming the P0171 lean code was there for a while, question is why?
Based on the short length of progression from 'slight hesitation under load' to full lack of power, would guess that the coil was starting to go and then finally went quickly. When it did go, my daughter was driving in town only. With me trying to drive it home, not sure if I ever got over 40-45 mph either. That could explain the lack of mis-fire codes. Guess we'll see soon enough.
