Kyle;
I doubt you need to replace the throttle assembly. Probably a problem
with the switch. You can order these from one of the list vendors (Bus
Depot, Vanagain, Volks Cafe).
On my van the throttle position switch had more or less fused to the
throttle body so I removed the throttle body and spent some time
cleaning the corrosion and dirt before installing the new switch. I
also found that the factory recommended settings were too tight and the
switch would not function consistently. When I set the gap I opened
the adjustment way out then slowly closed it down while manipulating
the throttle linkage until I got to the smallest gap I could get and
still have the switch do its thing every time the throttle linkage
returned to the idle position. Consistent function seems to be more
important than a precise gap. I use one of Darrel's Digitools but you
can do the same with a multi meter.
