DD15 problem

That sometimes happens to me as well but not for 6-7 secs maybe 1 or less. When did u do pm? Change your oil&fuel filters with good quality ones. Change your air filter. That sometmes works for me... if not have your dpf checked, still have problem? Check your injectors. Also there might be a short somewhere. Im not a mechanic or such but these are the only things i can think of. Good luck!

 

Is ur truck governed?

 

Jail Break is what you do with an iPhone.

 

Classic clutch switch symptoms. I bet that's what is causing your loss of power as well, progressive shifting is cutting RPMs.

 

Yea there's a micro switch that closes when your clutch pedal is out. It's a safety that cuts the cruise / jake when you depress the clutch in case you don't turn them off before you depress the pedal.
It could be clutch pedal return spring as well, if that spring broke, the clutch pedal doesn't come up quite all the way and won't close that micro switch.
Pop the cover off by you clutch pedal, you'll see the switch.

 

Throttle module? Or the harness leading to it? Maybe? Those things are all harnesses and modules and if you pressure wash the engine ther can be a lot of corrosion.
