Clean your throttle body. Disconnect your batteries for a while. Plug it all back up and let your PCM relearn itself.

Have you checked your FPDM? Fuel Pump Drive Module Located underneath the spare tire on the crossmember? A lot of people have issues with these during the winter months due to all the environmental factors. They tend to corrode and this can spark many issues. I wouldn't think it was your cats or you would have major loss of power. Just for S&Gs check this one part and if its corroded at all replace it. It will crumble in your hands.
