Ive had that problem on the 2A too. it got so bad once that it ground
to a halt on a hill and i had to get a tow home!

Pretty unlikely, though... most of the overall gearing variations are done
in the transfer box.

I actually thought that the 90/110 pre-TDi were the most variable, with the
110 having the lowest set of gears due to the weight and low power.

discos are all higher geared than 90/110s, especially TDi discos.


Lack of go can be down to slack in the "throttle" cable - check, with the
engine off, that while someone holds the pedal to the stop in the cab that
the lever on the pump is also hitting the stop on the pump... classic and
easily-overlooked problem.

Then check if it's actually hitting the 4500 revs it should do running free.
this can be a rather tricky thing to check... you can do it by ear by
comparing it with someone else's TDi which has a rev counter.

finally, if it never makes black smoke except on startup and burns clean at
highish revs a foot down under load, you can up the fuelling a touch.


another thing to check is the EGR if it has one - personally, my approach is
to insert a suitable blanking plate in the EGR pipe...
