there's a ball pivot at the end of the throttle cable where it connects to
the transmission lever.
I have seen these very rusted. Kinda buried up in there too, not real easyt
to see or reach.........and they never get lubed.......
might want to take a look at that part too.
I also make it a standard practice to remove the forward part of the
throttle cable from the white plastic tube in the van's body...........blow
that tube out with compressed air ........then feed the cable back into the
tube lubing it as it's inserted.
also the bell crank under the gas pedal.........and even junk around the gas
pedal..........all that needs to be checked.
to get at the forward end of the throttle cable, remove the spare tire,
remove the cover from the bell crank ( 4 phillips screws ) ........and clean
and lube that area over well.
