Re: Can someone explain this? LOL 
Sorry I wasn't clear in my first post. See my location, my stock C5 did not come with any O2 sensors in the exhaust. I think our version of PCM is not programmed to receive any reading from any O2 sensors.
Does anyone know what type of calibration could my PCM be using to determine the rich/lean conditions?
