While pulling my 26FT travel trailer the truck run fine for the first 50 or 60 miles then the engine

started to miss and run rough. The first time I was driving down I-5 after 60 miles the truck started to miss I pulled over. The truck Idled but a little rough,no engine light. I decide to go on, as I merged on the freeway the truck smoothed out. About 100 miles later truck starts to miss again. Again I pull over no engine light

nothing on the read a board the engine quits this time I am able to restart and continue this was 4:00 on Friday. About 6pm again it started to miss again I pulled over and the engine stopped after a few minutes it restarted I knew I was to late to get it to Vancouver WA. but tried to call the service Dept. but everyone was gone. Somehow I made it home, Next day I called two service departments in Vancouver,and Portland OR. Both said without a engine light on or nothing on reader board there wasn't anything they could do. They said to keep driving it and see if it happens again. So I drove it daily for one month no problems we had a camping trip planned for Aug.20. Truck ran fine the first 60 miles of the trip then there was three severe jerking engine misses within seconds apart when I accelerated the truck missed and stalled I just was able to get it off the road. I called three Dealers only one suggested I call Chev USA Thank you Chevrolet They paid to tow my truck to Dalles OR. This was Sat. no mechanics until Mon. The engine light was on when it was dropped off. Their diagnostic. machine could only read past problem that had occurred which were many. Anyway I'm picking it up tomorrow unfixed but the engine light is no longer on and hope I can make it home. I have another friend and his 2011 Dura 2500 broke down on the road near Yakima WA. They think it is a fuel pump problem and they don't have any techs that can work on it so Chev is towing it to Idaho. I love my truck I want it fixed. I am losing trust in it. Anyone out there have any similar problems please let me know. I have had a sensor in the DEF replaced, the oil pump replaced. Maybe its a lemon?

Is your friend's truck still in Yakima? If it is have him call Mobile Fleet service. They are a GM truck dealer with a service department open on Saturday. They know more about the D-max than about anyone.

 

Good luck

Thank you for your replies I'm just getting use to this forum, anyway I drove the truck home no problem about 100mi.Contacted my Portland dealer he said to call Monday the 8th see if they can figure a plan out. My friend had his truck towed to Idaho they said it was the injector pump and needed new injectors? He thinks he'll trade it in on a new one I'm not sure that's a good Idea it has 61000 miles this truck should just be broken in. I'm losing faith in the Duramax.

Take it to a dealer than knows how to use the software properly...sounds like a cp4.

 

Take it to a dealer that knows what the hell they are doing. Don't lose faith brother, you got a nice truck. Stick it to em, it's their problem not yours.

 

Test desired vs actual rail pressure. And injector balance rates including return rates.

      2010 Avalanche 5.3 not running correctly after engine swap.

      These show the problem and symptoms, and I explain things too. to clarify again, I did not change over any computers or wiring (with the exception of the map sensor). All of the computers and wiring are original to the 2010 vehicle   video 1 - background info/explanation and part of the problem   video 2, idle misfire   I think the reason that the MAP sensor is reading High is because the engine is misfiring so there is less vacuum...   Additionally there's a p0102 for the MAF low frequency, and a p0108 for the map high voltage.        Again, apologies for the somewhat long-winded explanation, it's a rather difficult problem to explain without going into the details.

      DFM Disabler

      You'd want the Pulsar to be safe.  That was the first product that worked for 10 speed trucks that they came out with.   Range Technology 22451 Pulsar LT for 2019-2022 GM Gas Trucks     That said, in the features description of the RA003B, it does list it working with 10 speeds.  However there are reports that the RA003B can cause some drivability issues on early 10 speeds.  So the Pulsar is the safest move IMO.      Range Technology RA003B AFM/DFM Disabler   Features: Range AFM/DFM Disabler keeps you in full power 100% of the time Simply plug into your onboard OBD-II port and it instantly begins working to eliminate the AFM system Disables Auto Start/Stop Blue LEDs The Range AFM/DFM Disabler does not reprogram factory ECU Works in hundreds of applications, 2007-2022, including 10-speed models. Leaves no trace, unplug it to return to factory settings Virtually no battery draw Fits all V6 and V8 General Motors (GM) active or dynamic fuel management vehicles, includes cars, trucks, and SUVs This device does not support the 2022.5+ Refresh model trucks or 2021+ SUVs To confirm your 2022 model truck is compatible with this unit, check your VIN. The 12th digit in an early model must be a '4' or lower Made in USA

      DFM Disabler

      I have a 2019 new body style high country with a 6.2l L87 and a 10 speed transmission code MQB. Looking for a disabler that is compatible. Most show it’s not. I watched a video on utube from Dons Life that says Ranges RA003B is compatible but when you go to Ranges website and check compatibility it only has a 8L90 trans listed which is an 8 speed.  I don’t want to buy the wrong one. Anyone have any experience with this situation?

      This actually happened. Be careful where you get your information re: gas price trends.

      I understand the principle...you don't want to spend $150 for a $0.02 piece of plastic or a little screw and perch thingy.   But this is a problem that looks like it can be reliably solved with a zip tie.   That might hold you over until you can score one at a pick-a-parts yard.
