I have an ‘01 5.9 at work with approximately 230,000 miles on it.
When you start drinking down the road the truck starts losing power and spitting back through the throttle body unless you floor it momentarily. Once you floor it momentarily it will run fine until the next time you turn it off for about an hour or more and then it will act up again.
I’ve replaced the PCM because it did have a code appearing about that and also replaced the fuel pump which went out just before I changed the PCM.
It doesn’t turn the check engine light on when it acts up like this and the light does work.
What could be my problem?

I know in the second sentence it reads “drinking down the road “. That should read driving but I can’t find a way to change that.
