The idle control unit in the passenger side area in front of the tail
light can get exposed to moisture and dust. On my '88, the female
terminals in the control unit plug have what looks like a very
aggressive "bite"; they seem to be designed to make contact with the
male terminal even if exposed to moisture etc. However. Cleaning those
connections can't hurt. Working that connector off the unit can be a
minor pita. Ensure that the female terminals in the plug stay seated
when reconnecting it to the control unit. Given the nature of the
"bite", the male terminal can push the female terminal out of the
plug.

From what I've read, the engine can run ok w/o the idle stabilization
system connected. Using power steering and other loads will cause the
idle to drop though.
