Okay guys I bought a BBK CAI about a month ago and a GT takeoff muffler and installed them, but shortly after that I started getting engine codes about the car running lean. It would from time to time shake and feel likes it losing power, and idle would be very rough at times. I have cleaned the mass airflow sensor and unhooked the battery thinking that would fix it but it didnt work. So I finally said hell with it and put the stock airbox back on and the same codes STILL happened. At this point im baffled any suggestions guys? I put some of the codes below there was another but it hasn't appeared again yet.
