Exhaust temperature variation
Flying my Cessna T210N has been a joy with a few problems alone the way that just seem to always happen with any GA plane. However the last 3 flights have puzzled. First leg in the morning the JPI showed exhaust temperatures all over the place with 100 degrees difference between cylinders, concerning but the engine seemed to run smooth as it always has. I continued to watch it carefully for the next 2 hrs. Arrived at my destination, a few hours latter I headed back home. JPI showed everything normal now with 30 degrees difference as it has for the last year or so. So I thought whatever was clogged cleaned itself out and all better now. Until the next 2 flights, exactly the same scenario. What is going on, is it the engine or the gauge?
anyone else seen anything like this?
