2009 Cummins ISX problems

My 2009 386 with a 550 ISX going down the road it will just shut off get real rough and then if I crank on it it will start but then runs for minute dies again

 

I had an 05 w9 with isx. There was a power wire that went from the starter motor to computer. It ran along the frame and had a spot of worn insulation. Copper shorting against the frame.

Took a engine wash to find the problem and fix for free. After 2 months of road calls and tows and $10,000 spent on mechanics.

 

Are you implying that this sensor can cause that sputtering? Did you experience this with your truck?

 

What's your current problem? What's your truck doing / not doing ?

 

It seems that the turbo sputters when I step on it pretty hard. I've already had the egr valve, harness, vpod replaced.

 

Explain stutter. Like, does it hesitate where your stuck in place for a moment then it releases or

 

Just quits while I'm running for a half a second then goes normal, it never does it when it's parked only while running down the run

 

Yeah sounds like a slight hesitation, how many miles on the motor?

 

800k I've had it for a year in a half don't know if it's been overhauled or anything replaced turbo back in april

 

Well, have you replaced the EXHAUST BACK PRESSURE sensor? I capitalized that because it's important, then comes the intake manifold air pressure sensor, and the egr differential pressure sensor: these are critical sensors that don't last forever.

If I had to start with one, it would be the exhaust back pressure sensor.
