I'm missing something. Robert said he was powered back and went further lean to the point he lost power. That is a cold cylinder so go after the wire and probe. Don't start pulling apart engines for a spurious signal that makes no sense at those settings.

Last week I had been cruising LoP and during the power back for landing Cyl #3 suddenly jumped 125F and sent the Chelton lady shouting
into my ear. That would not be unusual if I had failed to either further lean or go full rich but in this case I had leaned and the other 5 cylinders were OK. I leaned way back and really lost power and then went full rich, and it finally settled down. On the return
flight I reduced power
and carefully kept leaning and had no problem. Yesterday it was
deja'
vu all over again. Powered back on approach and only #3 went nutso until I leaned even more. On the return flight there was no
recurrence.
Does this sound like a problem with the injector, with the thermocouple, or ? ? ?
