The other day when I started the plane #4 EGT wasn't rising, per the engine log it was lowering to 285 for about a min. One I started taxing it started then spiked to 1305 and then over the next minute normalized in line with the other 5 cylinders.
Flew normal for the next hour and looking at the log nothing else erratic. Could this be a plug or lose probe or something entirely different?
