EGT #1, shows -99 deg. with the engine off (reading ambient air temperature). The rest of them read the ambient temperature correctly at 56 degrees, after second engine start & taxi run. It worked OK before, during and after the first engine start. I switched #1 probe wires to #3 at the harness connection in the engine compartment. The problem moved to number 3, so it appears the probe is bad. I removed the probe and cleaned it up but, no joy.
Do I need a new probe?
