I was headed back to the Pacific Northwest in my 89′Mooney 201 from southern Florida. Shortly after takeoff the EDM 700 was showing the EGT on cylinder #1 was running 240′ hotter than the lowest EGT reading of the other 3 cylinders.#1 CHT was slightly south of 385′. I watched it closely as I proceeded to Biloxi. I concluded it was likely a plugged fuel injector. When I landed I removed, cleaned and reinstalled the fuel injector. Problem pin pointed and solved by the 700. Excellent investment for any aircraft. Gary (Glassair)
