P0171 code still!!
 

Hello, I am new the forum. I have a 2003 Outlander. It love the car. It has never given me any issues until recently. Originally I had a p0101 and p0102 code. I changed the MAF sensor and Idle Air Control Valve. Now I am getting a p0171 code. According to my mechanic, there were no leaks. He kept suggesting to change the MAF sensor again until it works. I have swapped out two from Autozone already. After awhile the stores return policy will challenge me. I took it to Pep Boys and paid for the for the diagnostic service. Their tech suggests to change the EGR valve. I would appreciate any advice from the community.
