Your logic makes sense, the O2 sensor might be giving a bogus reading. I don't think you are running rich though, you could expect significantly higher HC and CO readings if you were. I once had the very same symptoms on my '87 240; I spent a small fortune replacing all kinds of parts, not to mention more than $150 on all those failed inspections. Finally, after much stress, the culprit turned out to be a $5 airbox thermostat.
