Default P0171 help!

Hey guys I have a 2002 wrx and I've had a p0171 for a long time. I just got it back from my mechanic yesterday and everything was fine til this morning on the highway the light came back on. My MAF sensor was just replaced and i had a vacuum leak that was fixed.I checked my accessport and it said i have a p0171 again. Any help is appreciated.

I have the same issue, but I'm positive its a vac leak, spray some soapy water on your fittings, you may have a hairline crack in one of your lines
