...then it seems that troubleshooting should focus on something to do with the O2 sensor?

If this is a dumb suggestion, please ignore. It's REALLY hard to provide third-hand advice over the internet...

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
