    I've got a 2017 T880 that intermittently jerks while accelerating (typically in higher gears, when coldish, or when loaded) and also has the occasional no acceleration when stopped (I've had to be pulled off weigh stations at the quarry just to have it go back to normal operations right after). I've replaced the fuel filters, throttle pedal assembly, and clutch (due to wear, not just throwing parts at this issue) and the issue has persisted before all of these updates and since. Any suggestions?

    I had a very similar issue. It was the wiring harness between the accelerator pedal and the computer.
