I went to Autozone to get the code read for my Check Engine light. The codes were P0171 and P0174 which translate to: System too lean for Banks one and two. What could be causing this error to occur?

Lean systems could be a faulty O2 sensor. Does the truck run ok or does it slug??

The Zone doesn't have the capability to run a data stream diagnostics. Find a good shop and let them diagnose it for you. They will look at the computer data and see what is causing the lean condition. Good luck
