RE: [DML] Idle Speed ECU

["John Hervey" <john@xxxxxxxxxxxxxxxx>]

Harold, The idle sensor at room temp is about 85 to 8700 ohm's resistance.
Just holding it in my hand for about 2 minuets brought it down to about 7200
ohms.
Sorry I don't have any good ECU's to part with but I might be able to find a
bad one if you want to fix it.
John

Subject: [DML] Idle Speed ECU

I think I have a problem with my idle speed ECU. I works fine for normal
operation however, cold idle speed increases during the winter didn't seem
happen - at any low temperature - like 20F, etc. So now that things are
warmer I wanted to check it - plus - with the right relay set-up I thought I
could fabricate an increased idle speed when I turn on the AC.

In any event, the wiring diagram indicates a simple trip of the thermistor
and there should be an increased idle speed. Problem is, I can't get the ECU
to increase the idle speed by simply crossing the two wires from the
thermistor - which I believe is all that is required. Thus, why I believe
that circuit is defective.

Does anyone have a working idle speed ECU laying around that they would be
willing to part with - cheap?

Contact me directly via email. My address shows in my post.
