EGT temps took longer to come down today?
I have a CTS and EGT probe. Have had them in for over a week and have been watching them closely as we all should. Turns out I was idling my truck much longer than needed before I got the CTS to bring the EGTs down. Anyway, up until today, I could pull in from wherever I had driven and it only took 30-45 seconds normally for my EGT to drop to 350. Today the high was 62 (not hot by any means), and I had to run an errand (to pick up some fuel additive) this afternoon. It's only 4-5 miles from work. I drove there, pulled up, put in park and waited for my temps to come down. They trickled down MUCH slower than normal. I didn't hot rod it on the way there. 2 miles of it on the highway at 70mph. It finally got into the 370's, briefly hit 368, then back into the mid 370's. I waited several minutes and they never got lower. I finally turned it off, went in, got my stuff and went back to work. Same thing. On the way home, same thing.
I had the heater on. Turned the temp up to 90, fan on full blast, didn't make a difference. Turned it down to 68 and fan on low, no difference.
Why would it cool down slower today?
