welcome, get it GDE tuned, probably a choked up MAP sensor, or too much soot in your intake. With a tune, it'll disable the egr and reduce the soot bigtime, improve your mpg, reduce your regens significantly, run better, run cleaner, keep your oil cleaner...
It's on my to-do list, I already took the foam off the egr side and the plastic cover is gone. Just need to get the foam off this side when I have time. There's a 1.5-2 inch pipe over top of the foam, what's that for? Can I disconnect it to pull the foam or is it a coolant line? GDE tune is...
but what do you do with the little tube, it looks like it's a bleeder tube for something?? I'm not sure what it connects to. Do you zip tie it to something else?
carlhenry, question for you, on the right side of the engine (battery side) there's a tube in the foam. I want to remove the foam, but what's the tube for and what should I do with the tube?
the fuel filters collect water as well, have you ever drained the water out? Let's hope that was the fix... the outside may appear clean, but I believe there's a few layers. They recommend changing the fuel filter every 2nd oil change.
have you ever cleaned the def injector? They get caked up in crystalized def within 6 months!! If they are fully pluged up, only a tiny trickle of def will go through. I wonder if that could throw a code. Takes <5 min to clean the injector and you can do it yourself if you have a steamer...
Does it still run or just have no power? If the reluctor wheel has gone, it won't run. That's inside the transmission connecting to the back of the engine and it senses rotation, but the wheels starts to shred along the outside and then the truck doesn't sense it's even turning...
if it has...
Tuning changes how the truck runs, generally, gaining some HP, reducing REGENS from GDE tunes, shutting off EGR, eliminating the lag on take-off, less oil contamination (oil stays a lot cleaner), better MPG. With a tune, you can keep the emission stuff on the truck but just shut off the...
you can leave the egr tube in place with gde (it becomes non-functional) but if you want it to look stock (some guys do in states that have visual emission testing inspections). Yes, get a tune if you want to prevent it from happening again. The soot is a killer of these engines.
