The AIS controls the idle of the engine. It will add or remove a controlled
vacuum leak to richen or lean out the idle as well as raise or lower it.
(Pretty nifty little solenoid.) Carbon builds up on the plunger after 20K
or so miles and causes the idle quality to deteriorate.

The idle motor is on the back of the TB (it's probably easier to remove
if you pull the TB off first). Pull it out and you'll find that the part
that does the sensing is coated with black soot. It stands to reason
that if there's gunk on a sensor that can be cleaned off, it shouldn't
be there in the first place. If a sensor isn't working properly and
can't sense what it's supposed to sense accurately, performance may be
affected.

What's it do? Got me. My Haynes manual is out in the Dak and I'm
having enough trouble sitting up right now, let alone walk outside.
