Stuttering 6.4L Hemi

[Aramco_Limited]

Has anybody else had issues accelerating with a stuttering truck? It feels like a power delay but stutters for 4-5 seconds before it finally just goes... it’s a 2014 3500 6.4L hemi with 154k on it.... I’m thinking it’s programming but that it could also be spark plugs, fuel pump and filter or fuel lines or injectors....

I also have a 2015 6.4L 3500 that used to do the same thing when I’d step on the gas to pass somebody on the highway... it had a power delay that I had to get programmed out... dumbest **** ever, first time it did that I ended up doing two circles down the middle of the highway in the winter as there was no power, no power, no power then boom all the power... fml ‍

The very first thing I would do is connect a scan tool and look at the fuel adaptive memory. If the motor is starving for fuel you will see it in the adaptive memory. Then I would connect a fuel pressure gauge and tape it to the windshield and go for a drive to see what the fuel pressure is doing while driving.

sounds like the fuel pump to me.
