I finished installing my LT's last week and as we all know you need the 02 sensor extensions. Well before the install I didnt have any problems with my 02 sensors, but now I have a code saying the circuit is low in Bank 2 Sensor 1. Im guessing the problem is I didnt put the extensions in all the way, or maybe I have a bad 02 extension. Does anyone know what sensor this is?
