Jeff,
There has to be something wrong with your cars emissions system based on the results I'm seeing posted here including mine. It's very possible that the ultra low miles on your car contributed to the issue. Constant cold starts and little driving to get the cats heated over 20+ years may have contaminated the cats and/or the O2 sensors. If I were in your position I would start with a bottle of the CRC additive to see if that cleans the cats and sensors as it says it does. Next I would change out the O2 sensors, they're not that expensive and relatively easy to replace. They may be leaning your motor out too much if they're off. Then retest to see if there is any impact.
Keep us posted.
