SES Light - P0171 Code To anyone who has had the P0171 Code, lean bank 1, definitely check for intake leaks after the MAF sensor.
Mine ended up being the PCV hose that goes to the passenger side of the manifold - the rubber had a small hole on the bottom that you could only feel, not see. I had damaged it after moving the hose a few weeks ago. I was amazed that such a small leak could freak the computer out.
Hope this helps you all!
