Hey guys I’m new to the 6.0 world and I’m in need of some assistance. I just bought a 2004 Excursion with 96k miles on it. The motor has been bullet proofed and maintained well. I’m friends with the guy I bought it from and trust him a lot. I was messing with the head unit and cut the ground wire for the parking break so I could make a new connection. Ever since I did that the truck has been smoking like a train and smells like unburnt fuel. I read around and cleaned the egr valve and it was not awful so I don’t think that’s the issue. I personally don’t think that cutting the wire had anything to do with it either. I have reconnected it and it still smokes white during idle and acceleration. A point in the right direction would be helpful and greatly appreciated.
