On my last flight #2 egt reading was 100-200F lower than the rest and irratic. This is a new occurrence, and a little disconcerting. Engine sounded fine and no other abnormals noted. I switched #2 and #4 sensors and verified that the reading followed the sensor. So, it's a PITA rerouting job for the new sensor.
My question is, how often do these thermocouples go bad? Should I change all four now? Engine is 314 hrs TTSN. Any insights would be appreciated.
