  1. 2006 Oxygen Sensor Wires Cut??

    Problems and Service
    OK...My girl has a 2006 cobalt LS and the other day I noticed the upstream oxygen sensor on the manifold...well the wires have been cut and I cannot find the plug to plug into if we were to buy a new one. She bought the car brand new. Nobody has worked on this car but the dealer where it was...
