Yea I figured it wouldn't be too bad to drive, but it was also 60• that day and towards the end of the ride so I don't feel like it was the cold. Too bad it's gonna be cold rainy and sleeting the next weekIf it's a O2 sensor code it should be ok to drive to the dealer. Low voltage/slow to react is not abnormal in cold conditions. They may check the connections and clear the code and tell you to ride and notify them if it comes back on. ....but I don't work to the dealer, just say'n.
