P0171 (B1 System Too Lean)

[Rescue84]

Is there anything I can do or at least attempt to do to remedy this? If not, any idea on cost/options? Thanks in advance.

It will one of two things: a dirty MAF sensor or an oxygen sensor. Remove your mass air flow sensor first and clean with electrical cleaner. If the problem still remains then it will confirm that the O2 sensor is NFG.

I will try this, thank you.
