Lambda series 1 - intermittent, I think Ainarssems said its only the heating element going out when it says "internal resistance too high"
Lambda series 2 - they only monitor the cats, sounds like heating is dead on those, but maybe they work ok once the exhaust warms them up? They will trigger the CEL in the dash though
Fuel trim - could be from bad MAF
Here are some ElsaWin factory test procedures for MAF, Lambdas, and Brake Light switch. If you can best check for yourself if these components are operating to spec.

Thanks for the PDFs. Some light reading for me tonight.
