About a month ago some punk stole my V-AFC

by cutting the main cord, I then had to uninstall all of the wires to the ECU and patch it back up. Since then it has been running rich and it is in the shop right now. The guys have put 8 hours of labor into it (only charged me for the original 3) and can not find out where or what the problem is. The owner of the shop said I might just have to buy another one. If anyone has had this problem or if you know what to do, reply...Thanks. One other thing, does anyone know where to get the V-AFC for really cheap, thanks.
