Looked at some of the other misfire threads didn't seem to find one, quite like mine. 2012 been running fine for 60k miles cobb with stage 1 on it. Was driving to work and all of a sudden I got harsh studdering to the point of almost stalling. I limped it back home and today when I started it seemed to run better but definitely still something going on. Cobb said misfire on all cylinders and 2 more codes i really wish I had, they didn't have descriptions though. Talk to the local subaru repair shop(not subaru but all he works on) said possible timing belt, taking it back saturday and having him drive it hopefully he will know what is going on. Any help would be great though.
