We’ve got a 2001 Dodge Ram Cummins Turbo Diesel.It has recently developed this bucking
behavior that seems to vary with the temp of the truck, temp outside, rpms and who knows what else. It feels like a lack of
fuel.It is worse on acceleration
over 2000 rpm, uphill, with a load. Some history on the truck – it has
been run out of fuel once, but all the injectors seem to be working fine.It also has an exhaust brake
installed.But the problem didn’t
occur specifically around either of those events, but definitely after the fuel
problem.
There has been no check engine light and Dodge says they can’t
do anything unless there are codes to diagnose.
I thought I remembered a problem like this discussed a long
while back, but don’t think there was a solution.Thought I remembered comments that Dodge
claimed the exhaust brake voided the warranty which shouldn’t be the
case.
