hey guys ive got an 05. ive just replaced the injectors with brand NEW 50hp injector from accurate diesel. they have been great until now. recently they have
started running rough on cold starts. ive got a fass fuel system with 2 micron water separator and filter. ive changed both and nothing. it only does it on cold starts after its been sitting for atleist 10 hours, rough idle with very little smoke then clears up along with roughness after 5 seconds or so? could this be an FCA? or rail pressure sensor? please don't everyone Hit the go-to response and say "bad injector"... that like saying a 6.0 powerstroke runs like crap and the first thing someone says without even hearin or looking at it say "blown head gasket". yea maybe its a bad injector but im looking for constructive TS advice not for someone to shotgun my entire fuel system and say replace the whole set of injectors.. any ideas??
