Need help on my (new) to me raptor

I found the old owner on here waiting to hear more from him. He said he had them check everything and replace everything they could think of so he traded it. Great!!!! Notnks is his screen name

Hi guys. New Raptor owner here and I thought it would be best to continue on this threat than start a new one on the same issue. I just bought a 2014 Raptor with 120K miles on it and when the car arrived from the auction in Texas (I am a CA Dealer) the check engine light came on. Vehicle is equipped with a JLT intake and Corsa Exhaust. P0171 and P0174 (Lean Bank 1 & Bank 2) is what appears. I went ahead and changed the Air Flow Sensor but the codes/lights came back on within 20 miles of driving. I wanted to know if anyone has any other recommendations that I can possible fix during the Xmas break as my mechanics don't want to bother with the car until the new year.
