Sorry, I should have clarified, I plugged that bypass over 4 years ago and I left it plugged after the rebuild. Heat issue is new. I was just splaneing how it is set up and did not clarify the timeline. It's easy to reattach and maybe I will give it a go, but that would be a strange turn of events. I have to say, outside of a stubborn air pocket it would be the only explanation. I'm going to swap probe locations and see what they tell me. Might be a bad mechanical gauge but they are usually pretty dead on.
