Truck has never give me any problems and has 200k on but now when going down the interstate u get up to 70 and it starts jerking and skipping u lay on in to it and get to 80 and it clears up. No codes truck has studs,egr delete. And this only happens every now and then with and without programmer.

Check your FICM voltage at key on, start up, and running. No less than 48 volts. Other than that must be injectors. Box yours up and call Warren Diesel.(814)-439-0218 They'll fix you up, ask for the powerstroke.org special.

Good luck! We're here if you need us.

Ficm is good and injectors are good

what did you use to test the FICM? And Injectors?

Your injector spool valves sound like they are failing. Mine did all the same things and when I just put new injectors in it stopped.
