Brian3676 Posted September 28, 2014 Share Posted September 28, 2014 I have been having some AF learning issues and am 99% sure I finally solved it. Just went to get some breakfast for my co worker and I, and I left work with perfect AF learning #'s, then when I got back in my car to leave and head back to work the car ran really rough when I started it and was super super rich, then smoothed out. I did a pull getting on the highway and my AF had my wideband pegged at 10, I usually run around 11 under WOT. As I drove my AF learning started diving again, got to work and it was at -14. Though oh **** finally I can check fuel pressure, got out and it was perfect 38. I then was playing and touched the MAF plug and wires to make sure it was not loose, and when I moved the harness, then car changed how it was running. I could sit there and move it and listen to it change back and forth. Short version, 99% sure I need a new MAF pigtail. Anyone know if Subaru sells them? I cant find one on the parts site....

norbs Posted January 10, 2015 Share Posted January 10, 2015 Hi, I'm having the exact same problem. Fuel trims all out of whack. Checked for leaks etc.. Then I moved the MAF wiring near the plug and all of a sudden all good. MAF voltage back down to where it should be. Did you find a new plug?
