Thank you.... I think I have a broken wire somewhere..... my OBD1 reader is not moving the temp at all it shows -38.6 all the time and the engine runs very badly.

You have an open circuit. Are you sure the sensor is good? These go bad like that. The PCM sees it is VERY cold and adds as much fuel as possible. This will ruin your cat in short order if you run it like that.
