I was just wondering how to properly fix this code. The P0071 code has shown up before on my wife's car and it was supposedly fixed by the mechanic. I just need to know how to properly fix this so it doesn't happen again. If it is the gas cap, we have replaced it before when the code came up and it didn't make a difference. She also tightens the cap more than three turns, so that isn't it either.

Could be a P0171 instead of that code you got-that indicates a lean fuel condition

Could be caused by one of the following below:

1.Vacuum leaks
2.EGR and PCV valve.
3.Low fuel pressure.
4.Dirty fuel injectors.
5.Mass Air Flow Sensor.
6.Oxygen Sensor.
