04 powerstroke misfire/hesitation/shutter when idling or higher RPM
2004 powerstroke has a misfire/hesitation/shutter when truck is traveling down the road moving around 2k RPM and then when come to stop the truck will lope a little and then slowly correct itself. I just had the FICM replaced and flashed. there is no check engine codes being throwing. I am lost at what it can be. The truck will start like to hop/shake when the misfire starts.
I am just trying to figure out what might be wrong before I spend a lot of money at nothing and still have the problem.

I installed a new ficm because the old one failed and Friday morning I went to start it and it just rolled over and wouldn't start. Old one it would miss really bad and had trouble starting. They had to reflash and update everything and it ran then. But that miss is still there. I will look at harnesses but does the valve covers need pulled for that? And idk if the Cps or maybe the ICP or ipr could cause a miss. Like I said no lights on dash or from scanner.
