Threw 3 SES codes today

While driving to install my RTE sliders the SES light came on again. This time with 3 codes:

P1415 Manufacturer aux emission controls
P0171B Bank 1 system too lean
P0174B Bank 2 system too lean

Two weeks ago this came up, P0734 Gear 4 ratio incorrect, and cleared it. I've driven about 50 miles since then. Do I need new O2 sensors? Thanks.

No, but you are boarder line in need of a MAF. The 3 usual codes that will show when a MAF is shot will be the 2 lean codes and a 734.
Better call Tony for a new MAF, then get your codes cleared.
