Hi, I’ve got a DA40 with an IO360 and the G1000. The EGT on cylinder 4 climbed off scale with no change in CHT. Happened out of the blue on a local scenic ride. No change with advancing mixture. Any ideas?

I had the exact thing happen in my DA 40 IO-360 when the engine was, I think, about 60 hours. It turned out to be an almost microscopic piece of plastic in the injector. Cleaned the injector. Back on my way only two hours late.

Cleaned the connection with contact cleaner. Came back to life. Odd!

Recently had a similar issue with one CHT being all of a sudden higher than the others. My partner in the plane ran some tests and put together the attached presentation which I thought was excellent. Replaced the spark plugs for that cylinder and issue is resolved.
