Subject:throttle body modification question 84 to 85 (amended)
From:Dave Caston & Sherrie Payne

In the on going problem solving to solve the idle hunting problem present
on Vinnie, We have replaced the original throttle body with a modified 84.
This was due to excessivly worn components inside the bushings and
housing/plate areas. It now looks just like the 85 did exept for the plate
design inside- flat brass looking on the 84 v. tapered aluminum on the 85)
and now it is herky gerky at real low RPM's instead of the smooth
transition that was present on the 85 throttle body. My mechanic did a
great job-IMHO-on the modification and I wonder if the stiffness in the
accelerator pedal is common among 84's or does this throttle body require
some more tweaking. He did adjust the throttle stop screw per Bently but on
the bench not on the van. Does that make a difference? Are 84's sort of
gerky at take off sometimes or at real low RPM's such as cruising around a
parking lot looking for a space?
ANd one lst thing, on both the old 85 and the new 84 modified throttle body
I can crank the idle adjustment screw all the way in and the an will still
run. Some time prior to all this, this was not possible. Any idea if this
is normal or not and if not where do I start and what do I do?
Looking for the last pieces to the puzzle,
