It's safe to assume that the truck doesn't start right?
It sounds like you have either a bad exhaust backpressure sensor or a bad EGR valve. Both of these will set the codes you are seeing and both will make the truck idle but not accelerate.
If the code sets immediately upon clearing them I would suspect that the backpressure sensor is the culprit.
Please let me know if you need additional info.
