You need to find out what code it is setting and then it will most likely be a sensor that needs replacing

i have sen co workers(heavy duty techs) work on diesels fords. its not easy to do injectors on those.you attempt to do it yourself and youre gonna create more work and more problems.

It is the fuel heater, All you have to do is unplug it.

its still under warrenty. take it in

You can check your motor mounts. They can cause your engine to shudder. With the hood open, have someone shift into drive and watch the motor. If it rocks severely more than likely your motor and/or transmission mounts are broken or ate bad.

Sounds to me like there is a wire or some wires that get caught up in the shifter linkage under the dash. Hope this will help out. Best wishes.

I have a pickup that this happened with. I just had to look underneath, find the dangling shifter linkage and plug it back in. Make sure the hardware is there and doesn't look stretched.
Good luck!

have your fuel system vacuumed out our excursion did it as well the injectors are not at fault it is the fuel lines
