One thing i dont do is check to see if my PCM software needs to be updated
really dont know how so I jumped to the second step
Common Problems That Trigger the P0171 and P0174 Code
PCM software needs to be updated
Vacuum leaks (Intake Manifold Gaskets, vacuum hoses, PCV hoses, etc.)
Mass Airflow Sensor (MAF)
Plugged Fuel Filter or weak Fuel Pump
Plugged or dirty Fuel Injectors

For those codes I would try cleaning the MAF
