That's not to say Johnny's sensor isn't bad and if it is that heat didn't cause it, but I do know Johnny ran leaded fuel a bunch in that car many times when he worked at the airport and that IS something would greatly affect O2 sensor life.
This could be true, but I don't feel like the sensor would start behaving again after going WOT if it was wearing out. Also, the sensor looks to be in the same shape as the one in the Spyder which has never seen leaded fuel. "Looks" being the key word. haha
