        As to the unknown spring and arm, I have factory cruise on my 91 and it
doesn't utilize this mechanism; I have one too and it isn't connected to
anything.

        I have seen similar apparatus on governor controlled engines; and my
guess is that is such a governor type device. If I'm not mistaken the
arm will pull the throttle valve closed, but will not push it open.


        As to gaping the micro switch, .002-005. tolerance, That may be the
range of control available by the opening gap of the throttle butterfly.
 In other words after that amount of movement, more air is able to flow
past the butterfly, and the engine is at a higher RPM, so no need for
the Idle stabilizer to try and correct. MY guess.
