This sparked an interesting conversation. My old man said he noticed this on both his 2011& 2016 Super Duties (prolonged high idle). Both ordered and bought new. Said his older trucks didn’t do that. And it’s got me thinking, my old Explorer idled right down too as far as I can remember...until I junked her. This Expedition has always warmed up a bit longer. After that initial start of the day it seems they don’t do the elevated idle again.
Did Ford do some changes to the ECU to keep these idling higher longer?
