gaethzac000 Posted August 1, 2017 Share Posted August 1, 2017 Just for some background, I have a 2006 Legacy GT SpecB with COBB downpipe and full exhaust with COBB Stage 2 tune from Accessport V2. So I saw that I was throwing a code so I checked what code it was with my accessport and found that it was the P0171. I read on the forums a little bit to see what it might be so I checked my airbox and cleaned my mass airflow sensor and that didn't fix it. Then I saw that a lot of people had vacuum hoses blow off of the blue T connector underneath the intercooler. So I took off my intercooler and I checked those vacuum lines and they were all still connected. So as of right now I have no idea how to fix this and was hoping someone could help me find the next step. The only thing I've noticed when driving it is that when I'm staying at one constant speed it'll try to hesitate like it's not getting power. Thanks.
