Weird jerking symptom
Me and the wife just now noticed this issue after about a week of owning this 6.0 f350 auto 4x4. Leaf spring front and rear. Long bed. Listing all this stuff because not sure if it matters.
Around 50mph if we drive normally about 1500rpm the truck seems to jerk a little as we climb in speed. If we get the truck into the 2000rpm range it goes away.
Not sure if it's suspension, transmission or engine.
Anyone have a clue what it could be. ???

Each time I've had this happen I've ended up having an injector fail, it always happens on the low end of a gear with light throttle. I would imagine other things can cause it also but this has been my experience.

Do you have a scan tool that can read live engine data? If you do, watch your high pressure oil pressure and IPR duty cycle value.

All the times it happens on my 03' Ex it is an injector. The problem is it hardly ever sets an injector code. I always get a p0603 code and nothing else. Only once did I get a contribution code or a high/Low voltage code for the injector.
A sticking turbo will give the same symptoms. You usually get a p132 code with an over boost code though.
