    double check the wiring make sure the connectors are good and the prongs are in good shape, autozone is also known to having bad sensors or a batch of them.. might wanna look in the a oem gm sensor.

    What did you torque them down to? 15 ft/lb is what gm calls for. I've read and been told that over-torquing them can cause problems.
