i have a full diognostic file that has every code,possible causes and solutions that would help you out but its too big to upload so if you want PM me your email and i can send it that way.sorry i cant help out now.
Only thing under the hood is a CAI. I checked the plug to O2 sensor #1 last night (which I couldn't get disconnected) and noticed that the breather tube from the CAI to the valve cover was disconnected. I think I forgot to hook it back up when I took everything off to clean the EGR the other night. I wonder if that could have triggered it? I kind of doubt it.
