Subject:      help with function of idle stabilizer
Content-Type: text/plain; charset=iso-8859-1

I have been trying to root out an intermittent high idle (2000 rpm) on my 86 2.1
.

- I have pulled the control unit for the idle stabilizer out from behind the
tail light and opened it up.  It is less than 3 years old form the receipts I
have from the PO and it looks all shiny and new inside still
- I have changed the idle stabilizer valve with a spare that I have.  No effect.
- the Temp II sender was changed last year (maybe year before) - could it be
bad?
- the idle position switch on the throttle body seems to be working fine and
clicking at the right spots.
- disconnecting the idle stabilizer valve seems to fix the high idle.

How do you test the idle stablizer valve itself?  If it hums, is that good
enough?

What are the other inputs into the idle stablilzer circuit?

I get this high idle when warm and cold on an intermittent basis.  Some times,
pressing the throttle and releasing fixes it, other times not.  The high idle
appears when it's hot outside, or cold(er) outside, but not always.  I'm a bit
stymied and since we are headed on a two week road trip, I'd like to have a
handle on this.

Please reply via p-mail as I'm in nomail at the moment.  TIA!
