So my engine check light came on. I had the code read at autozone and it was P0171/ air fuel metering. What is that? is it my MAF or is my intake moving to much air. Helpp.

I am not sure what exactly could be causing this code, however I looked it up in my scan tool and it said "System too Lean (Bank 1)". Someone else more familiar with it will have to answer why. Hope that helps a little.
