Developed isolated high EGT on cylinder #3, reading 300 degrees higher than the other three EGT's ( 1650 compared to 1300-1400 on the others). Upon initial startup, #3 EGT immediately displays 600 degrees, before others register at all. Replacing with a new EGT probe has not altered the situation. Engine runs smoothly, with less than 100 hours on new cylinders. Normal CHT's. Is this an electronic issue? How to correct?
Thanks,
