    Exactly what should I be looking for with these potential grounding conditions they refer to in the shop manual? Does this mean I need to trace each of the little wires looking for a short or is there a better way to scope this out? Or has the sensor gone south? None of the other threads with the error condition say anything of value. I've been riding it like this for over 3 weeks given the one suggestion you need to have at least 5 restarts. I've got well over that and it's an active code I can't clear with my Dyno-Jet tuner. So what's the trick to clear the code?

    Well, a new O2 sensor fixed the issue for what it's worth.
