RE: More O2 sensor news
I don't think that the sensor normally goes to that low a voltage ... (I'm
not an expert on that, but it doesn't sound right based on my understanding
of how the thing works). If I saw something like that I would actually
suspect that there is an intermittent connection to the sensor or a bad
ground somewhere ...
Good luck finding the source of your problem Brian!
