other trick is to FIND it. The pdf shoes it on the firewall near the
brake booster. Not on this car. Probably under the pass side dash.
Yup. See:

For new and
there is still a possibility that the wires are hooked to the ICV
backwards, as it does not have an original plug, but red individual
crimp on connectors. there does not appear to be any orienting lug
on the ICV, so I tend to think the it does not matter as to polarity.
But that is an untes
Tried hunting vacuum leaks later today. The boots for the ICV are a
little loose. I pulled the one off that goes straight down from the
straight end of the ICV. in the end, the idle is now higher, about
2500. There is some form of boot that goes under what I would call
the throttle body (
Makes no difference. there is a pulsed signal to it about 60 cycles
and about half on half off at 1600 to 2000 rpm. the wire to ground
is ok. I know the ICV is bad. still have to test the oil pressure
switch, wires and relay.
If the car is running and you unplug the ICV, does it do anyt
If the car is running and you unplug the ICV, does it do
anything? IIRC the quick and dirty test is if the idle goes way
up then its good. If it does nothing, its bad.

Put the wires back on the ICV to start the engine and do the test of
the vacuum switch. No start, so obviously the ICV did not open up.

Indicates ICV is not completely dead. It might be sticky,
and unable to move smoothly as it should. Have you cleaned
it out thoroughly with brake cleaner?

OK, found the sensor or the rear of the right head. 0 ohms cold,
the switched to infinite as the engine warmed up. tried jumping the
two sockets in the plug. No difference, so I figured the $800 idle
control valve (ICV) is defunct.
Then removed the wires to ICV and with the engine running
Well guess what: Rusty's website says that idle control valve is
$800 or more at the friendly local stealership. Only $350 from Rust
man. for a $25 part. Ok, to be fair if I call him he will probably
sell it for less, but $300 is still a lot of money to slow down the
idle. How bout I stuff

OK, I pulled off the wires, and one terminal came off the wire.

a 12v pulse signal at the "hot" wire and the other appeared to have
continuity to ground. all the hoses and vac look ok.
So I thought maybe the wire that came o

Thanks for the clue. I may be sending you an email to see if you
have one for sale. Or maybe that realy and an OVP relay.
Now I think I have all the pieses out together to understand how it
is supposed to funtion, how to find the parts, and how to diagnose it

Kaleb sez:

Measure the voltage coming off of it?
So the wires are fed power by the OVP relay?
The computer that monitors and regulates idle speed is powered
by the OVP. The computer (idle speed 'relay') powers the valve.

Yes.
What are the connections?
Two large air pipes, one to each side of the throttle plate.
Two wires.
I thought I was told that the OVP relay played into this somehow?

IIRC, yes - it's as simple as the SL. I also don't think the TC has a drain
plug.

Idle air controller isn't able to shut down quite enough
to keep enough air out to keep the RPM's down when unloaded?
Could be air leaks, cloggy valve, or even the controller messing

a mechanical problem. (Unplug idle air valve, and
Check the condition of the idle control valve, make sure it's plugged
in, and that the hoses are good. Clean it with brake parts cleaner
if the hoses are bad -- block one side, fill it up, shake it a bit,

You're right on Fred... most likely an issue with the idle control.
The idle valve looks like this:

Take a look at it and all the rubber hoses that connect it. Anything
dried or up cracked should be replaced. Most likely, it all needs to

this car seems to idle very high when it is in neutral. It is like
the high idle never goes to normal idle. When you start the engine,
it goes to about 2000 rpm and stays there. When you put it into D or
R, the engine slows enough to be ok. I did not check the tach, but I
would say 750 to 1
