Shawn, that is kind of normal for a switch to ohm out with a minute
resistance.  Try unplugging your idle stabilizer on the top of the
engine while it is running and see if this lets your idle go down to
where it should be.  It could be the idle stabilizer itself or the
control unit (the control units are the most common source of the
problem in my experience).  You can clean the idle stabilizer out with
some brake cleaner and some times this will clear the problem up.  Let
me know if I can help you further.
