So I noticed the other day after the truck was at operating temp I stopped at a friends house (leaving the truck running) After a few minutes we left to go to town and I noticed my eot was @ 20-30 degrees cooler than my ect (190-195). Before I stopped at his house my delta was normal @ 5-7 degrees apart. So we got into town ate lunch did some more running around and it was reading fine again. Now on my way home this morning from work (about a 30 min drive) temps were fine till about 5 mins from my house and I watched my temps go from 190-ect, 198-eot to 190-ect, 174-eot and stayed there till I got home. I'm just wondering if my EOT sensor is going out? Any help would be appreciated!
