Could be your throttle pedal sensor/resistor is going bad (no cable) since it’s OK using the cruise...not a fuel problem.


This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.

Is the Allison shift pad changing gears that it indicates immediately before this happens?

If a single window-- is it still showing 6 when this happens or the "engine brake pre-select" gear?

If two window, is the left window doing the above?

If so, that would suggest that the exhaust brake may be coming on and not disengaging.

Agree with others. Sounds like your Jake brake is hung in the on position from time to time. The cruise doesn't let off enough to activate it , but you do when you let off the pedal

Exhaust brake is where I would start .
The exhaust brake closes to help you stop and should open back up when
you resume going . Sometime they can hang up and will not reopen properly .
A special high temp lube is necessary to lube it .
You could move the brake back and forth by hand while lubing it in a matter
of minutes .
Mine is readily accessible thru the floor hatch in the bed room .
The brake gets very hot so do this when its cool or be very careful .

The Freightliner Help Desk will help you troubleshoot this problem.

When you call, have the last 6 digits of you VIN number handy because they will ask for that to allow lookup of your chassis info. Up through 2016 this was a free service, so I assume it is still free.

These folks have helped me several times.

I had this same thing happen ONCE. Came off the cruise control and hit the Jake brake and it went straight to idle and no more. Turned it off and sat awhile thinking and it started up and has been fine every since...Seems mine has no throttle cable and the module that controls the throttle is mounted back on the engine. They told me it re set when I turned it off and back on but could be caused by a brake light not going off.
