Hello Finn. I replaced both EGT probes last year. If I remember correctly one was reading higher than normal and around 1800 F.  I think it was intermittent for 2-3 flights before locking in at a higher reading.

On most recent flight from Shady Bend to Clearwater, the engine monitor alarm kept going off. EGT on rotor 2 higher than rotor 1 and higher than 1800F, intermittent.

First I thought I should replace spark plugs, but reading up on SAG postings, it appears that bad spark plugs reduce EGTs and RPM.

So, should I instead look at cleaning injectors?
