I have an 08 6.4 Tuned with SCT and DPF Delete. It just started losing power. When you first take off from a cold start it runs fine and after its a minute or two it has absolutly no power. Took it to the ford garage and they said that my egr valve was stuck. Would this cause a big power loss?
well went back to the garage today and said the egr valve didnt fix it!!!! Said it ran fine for a mile or two then fell on its face going up a hill....I'm carrying good fuel rail pressure and plenty of boost..Wondering if it may not be my injectors?
I'm not sure exactly what sensor it was it should be here first thing this morning! Would that sensor cause my truck to do this? I hope this fixes it because I bought a new 5th wheel camper and am supposed to pick it up today and head to tunkhannok, pa to work in the morning!
