So, on flight today the left digital EGT gauge starting acting up - went down to a very low temp and then up to reading correctly again etc, but was mostly stuck on . the low setting. After some power changes it seems to quicken to and come back and show correct again, only to after awhile drop down to radon low number again.
A problem that's common after sitting for awhile, perhaps? Should I just clean the cannon plugs? Anyone experienced something similar?
