hey ive got an 03 f250 superduty and a few weeks ago i was driving home pulled to the side of the road to get a phone call and my truck sounded like it was missfiring and started to shake very rough so i quickly got it home and it barely made it up hills with no power at all, took it to the mechanic and he said it was my wiring harness, so i replaced it and it took weeks to get here and i finally get it in and my truck still seems to be missfiring ad idleing very rough, i replaced my oil less then 1000km ago and ive had 2 injectors replaced. ive talked to a few diesel mechs and he recomended to put some hot shots in it and see if that helps it out. i know some people out there hate hot shots so dont turn this into a hate forum, i would just like any helpful information thanks!
