I have a 2007 f450 diesel w a 6.0l engine I am having unusual problem.

What is your question?

Truck has 97k miles and has had some major work done..injectors, After picking up and driving +/- 30 miles, the ck engine light comes on,and the gas pedal is unresponsive. Then w no rhyme or reason, will come back on. From that point it runs rough and can happen again. It also has the opposite issue and the engine will race wo any pressing of the gas pedal. Almost like it is possessed. Truck will usually start up again after the episodes. I replaced the throttle sensor, main computer, and glow plug sensor. I have only driven from mechanic to mechanic. Any help is appreciated.
