I have been having a binding problem with my throttle valve since before
Christmas.  I clean the throttle valve with some brake cleaner and that is
when my troubles began.  The next day the van would not idle only die.  I
found that the idle position switch would not work unless you slammed the
throttle plate shut or gave it an extra push.  I was going on a trip so I
adjusted the switch so that it would close when the throttle was slowly
released.  This fixed my idling problem, now I believe I am having some other
problems because the throttle is not shutting all the way at idle.  I am also
noticing that after the van warms up a bit, the throttle switch is no longer
being activated unless I kick the pedal (using my digitool to determine
this).  I have checked and readjusted the throttle screw per Bentley with no
luck.

The throttle feels really stiff and binding.  I cleaned it up with scotch
brite inside and lubed it up with LPS 2 (avaiation grade lubricant) but it
still seems to bind.  I also hear a crunching noise (like dirt) when I move
it.

I checked it for play and the shaft doesn't seem to have side to side play
but does move up and down a bit.

Has anyone else experienced this problem?  How did you solve it?  I am
thinking about taking the whole thing apart and cleaning and lubing it this
way but I wanted to check to see if there were any alternatives before I
tried this.

Thanks,
Ken Wilford
