Check Engine Light Driving Me Nuts

Hello All,

I have a 2000 2.5 5 speed with 138K on the clock. I have done a complete tune new wires New plug both sides New K&N Air filter I thought that it was causing the problem so I went back to Stock Air filter I have replaced the MAF sensor and the Front O2 sensor found a vacuum leak at the heater valve corrected it but I am still getting the Code P 0171. I have a code reader my self I can clear the code but I have to tell you is comes one like less then 20 min of driving.
