There is nothing wrong with the 100oct. gas. Its only the leaded high oct. gas that will kill O2 sensors.
My O2 sensor is the same way, but it only throws the lean code when I let it idle for a while.. I'm going to try and replace the O2 since I have ran 2 tanks worth of 116oct. leaded gas though it..
