partially warmed up at time zero.

Wow, if the IC itself is at 55C after a minute or so of idling, that's bad.

55C is 131F, which is where temps behind the IC went a minute or so after shutting down the engine during my data log. But while I was driving, even sitting still, the air in the engine compartment didn't exceed 115F (46C)...

Fixture is brass or copper I think and came as a kit with the probe. The pre IC side probe is exactly the same.

I'm just grasping for straws... I don't want to believe the IC is that hot...

I'm going to load all this up on my laptop... I'm traveling later tonight, so I'll have something to keep me busy if the in-flight movie sucks...
