Engine missing after upshifting

mine does it too. keep the rpms up, try not to lug it down so bad when you shift.
mines been doing it since i nought it. two years. ive found more that do this then that dont do it. freightliner will just try throwing parts at it. expensive parts. the only thing ive heard that clears it up is a new egr and then only for awhile.
just lesrn to live with it. im sure not replacing a $4500 turbo that doesnt need replacing

 

I have been driving an 06 FL Columbia for a larger co. Not going to bash them here but the point is every one of the trucks in the fleet with egr DD60 do this. Most noticeable after idling or a restart such as after a fuel or meal stop. It will get worse as you get more soot buildup. Egr has no place on diesel IMHO. Either learn to live with it, or change the engine to a non egr. Or every so often replace the egr valve, egt sensor, turbo pressure sensor, and clean out all the egr tubes and the intake manifold. I am buying my first tractor, been a co driver for 10 yrs. Was given the choice of Detroit or Cat power. For me after driving and fighting with the dd60 egr system cat was the easy choice. Especially since the one I'm getting is pre dpf.

 

IMO, low fuel delivery pressure, bad fuel pump ore clogged fuel filter, ore air sucked in system..

something simple

 

All that has been checked and it is good. When I said every ds60 in the fleet I'm saying over 300 units. This is not a few its EVERY one of them. Some have blown turbos from the severe soot buildup causing the turbo pressure sensors to read inacuratly. I am done with Detroit after having dealt with this and seeing all the drivers in the fleet go through it as well. Wish the epa would pull their head out and reduce emissions by reducing time sitting in traffic instead of screwing up our engines.

 

Mine did the same even after replacing the turbo and many other parts. Finally the Detroit shop took the time to adjust the turbo and voila, no more miss/puff/cough.
It's not a difficult adjustment but Detroit says that they are adjusted at the factory and don't need any further adjustment. Mine sure did. What a difference it made.

 

i got the same exact truck '07 and all, and it does the same thing


MedicineMan: I can't not let it lug so low, we are governed at 1700RPMS lol

You stole my answer.But i think u are right.

 

Thanks.
After driving it for a few days I think I know what they did.
Everyone want's big power at the top end so they set the turbo at the factory to give it to you. After the adjustment I now have good smooth power from a dead stop to around 1800 and then it starts falling off. This fits my driving style perfectly as I rarely rev it that high anyway.
So now I have great torque at the bottom end where I need it and smooth power throughout the powerband.
I'm happy with it.
