2004 F350 6ltr runs strong, excelerates strong but when getting up to 50 + truck starts to chug pretty bad. If I let off of the gas it seems to stop, if I excelerate past 60 it seems to stop. I am leaning towards the transmission or possibly the converter going bad. Anyone else have this happen?
**new FICM and 4 injectors have already been replaced.
The programming is stock for now. I thought about the turbo to and start to play with it. I disable the vgt. Still had the same problem. @mblanken it is kind of hard to explain. I use the term chugging cause that is how the misses describes it.It is almost like it is bucking. I have had a carrier bearing go. Does feel like that.
I was leaning towards tranny thinking maybe the converter is not locking up or slipping some how.
Just wanted to thank everyone for their help. It turned out to be number 1 injector. 2 hours later I was hauling ***. Thanks again. Now to install my SCT livewire. Cant wait to see how that works with my 39 foot fifth wheel.
