My Skyview showed rapid movement between 300 and 550 degrees then it went out of range and stayed that way until landing. While taxiing all temps were normal and #2 egt stayed normal throughout the flight. When I pulled the cowl nothing looked cooked and sensor wire looked normal. Compression seemed normal when I pulled the prop through eight or ten times. I will swap egt sensors 2&4 next flight. Any other suggestions?

Only bad probe wiring or a failing exhaust valve will cause rapid fluctation. In the later case it will be a saw tooth pattern of maybe 50 degrees, and your problem is far more likely to be a poor connection to the probe.
