2004 F250 power stroke 6.0 hesitate off the line to get it up to speed and it runs strong has lots new parts sometimes hard to start. I’m sure if good diesel mechanic or somebody that has knowledge of these something small. I’m sure you could just make it run good I’m just not a diesel guy anyway got about five grand into it. I’d like to get that back out. I need to get it gone four-wheel-drive works good everything on it works good really other than just being little bit hesitant
