Tb48 jerky low range

[Avo]

The 4.8's are drive by wire aren't they?
Might be the Accelerator Pack, the ZD30CRD's will do the same if the pedal sensors are dirty/worn

Not uncommon for CRD owners to put some sponge under the pedal or jam their foot against the kick panel to 'damp' down the human input

crd owners are begging for power,,,i need to put a hole in the floor so my pedal goes further..
do the 4.8 have a throttle control..like a choke but not a choke..i do remember readingh something yrs ago regarding high country climbing and a steady throttle...and the talk about throttle control..like a choke but not a choke..idle up maybe.....
