  1. Gen1 Service Issues
    Hi all, I have a 2012 Cruze Eco MT and the CEL just came on at about 85k. The codes I got are: P0107 - running lean (pretty straight forward, plenty of other people have had this as well), and B0307 - Control head #3 (rear) feedback circuit open Can anybody help diagnose the B0307 code please...
