Should I be Concerned?

Had a Powerstroke Certified Technician R&R my fuel filter housing, new hose lines, filter, drain plug, etc. Also replaced the Injector Drive Module, Crankshaft position sensor, and the Exhaust gas recirculator. Ran great for a week.
Went to start it this morning and it idled real rough!. No power. Later in the day I started it again, same thing. Let it chug at idle for a while, then put the pedal to the floor and after a short while the rpms increased big time and it idled smooth. Drove around the block, OK.
I'm guessing that one or more injectors picked up some crud, and now it's flushed through???
Wishful thinking?
How about I add a small shot of VMP Naphtha? (A powerful crud solvent) to the fuel tank.?
Thanks in advance.
Dick

NO, do NOT add that to your fuel.

Why was the injector driver module replaced? What was it replaced with?

You also do NOT have a EGR, what exactly did he replace?

You also don't have a crankshaft position sensor.

He installed a reman IDM because it would not start.
He also according to the bill, installed a cam sensor, an EBP sensor, and a glow plug relay.

Thanks for asking.

I'm saving up for a code reader, so don't know if any were thrown.

109,650 miles.

Sounds like the GPR if it runs fine when warmed up. Just because they replaced it it doesn't mean that it's working.
