By on top of the cat, do you mean between the cat and the engine, or the sensor is actually plugged into the top of the catalytic converter itself? I would think that the down stream sensor would be AFTER the cat, as it's measuring how effective the cat is at doing it's job...

I meant to come back and update this thread. The spark plugs spacer did the trick for me and has worked consistently for over 2 years with no problems.
What an update.
Do you have a description or picture of the spacer you used? I've got a similar problem and was considering one of those, but all I see are for the threaded o2 sensors, not the flange-mount my '03 100 uses.

I bought a threaded spacer for my 07, and wouldn't know what to suggest for a flange mount sensor sorry. By the way the spacer is still working fine for me.

Kinda late to the party but just had the same issue after getting my emissions done on my 2000 100 series...
Passed but all 3 codes showed up after I drove it after 10 miles. Talked to a buddy of mine and he said replace your gas cap. $14 later and the codes all cleared as soon as I installed the new one.
The gas cap pressure test can mess up the OG gas caps...

Thanks for the reminder, hopefully it'll help confirm this to someone that's searching for the answer and a quick fix.
Just had the same, check engine light and VSC trac and VSC off lights. Found this thread. Resecured gas cap, disconnected battery for 30 min. Lights were off initially then came back on. 17 yr old gas cap. Put a thin film of oil on the gasket, resecured it. Lights off. Old gaskets might need a little oil.
