Blumpkin Posted April 8, 2013 Share Posted April 8, 2013 So here is the story, I was driving around last night and the car started to idle rougher than usual so I hooked up the AP and started looking at some numbers. The AFR hopped up to 20.3 as opposed to the normal 14.7, my boost went from 17.5 at peak down to 8.9 and when I pulled codes I got that I was running too lean, as obvious by the AFR and misfire on all 4 cylinders, anyone got any ideas?
