Default LIMP MODE!!!

my truck keeps goin in to limp mode from what i hear... she says its running right and it is 20+ degrees out... but i had her dump diesel 911 in it and it cleared up for awhile but it still keeps goin into limp mode??? all i can think is the fuel filter... but its hard to tell without looking at the truck... IM HOPING AND PRAYING ITS NOT THE INJECTORS!!!!!!

It's not the injectors, well does it feel like it's running on half the engine?? Sound like a powerstroke?? could be the # 2 or 7 injector connector.

Check engine light?? Fuel filter will cure most problems, but it could be a connector...... wait a minute, arn't you the one being used?? Your truck just needs a MAN to drive it, not a wuuuuuusssssspppuuuuuusssss.........

idk what it sounds like she said it sounds normal and i did have the powerstroke issue already and i put in a brand new injector harrness... (made me sick to my stomach hearing my truck sound like a powerstroke )

i told her to limp it back home so im praying that its nothing major
