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???
How about I add a small shot of VMP Naphtha? (A powerful crud solvent) to the fuel tank.?
Thanks in advance.
