No idea how many miles are on the O2. I'd bet it's most likely the factory unit (the plugs I replaced at 192k were so worn that I think they might have been factory plugs, just to give you an idea of how neglected this car had been). Anyhow, that's why I wish I had a scope. It would be nice to actually watch the O2 switching.
