1991 Accord Idle control
In the 2.2 liter, 1991 Accord engine the idle air control (IAC) is located
on the intake manifold, a black cilindrical electric motor looking thing.
I have once read on this newsgroup that the idle air control valve can be
cleaned, should be cleaned when the engine idle is not steady.
When wanting to do this, I noticed that the black cilindrical thing cannot
be removed by itself. Also coolant lines are running to the IAC. So now I'm
wondering whether I can remove the whole IAC from the intake manifold,
without having to bleed the coolant?
Any tips, advice?

Re: 1991 Accord Idle control
My '94 Civic has the same setup, IAC on the manifold just behind the
throttle body, and coolant running through it. I have never removed it,
but I have removed the throttle body which also has coolant running
through it. I did not drain coolant, and did not bleed the system
afterwards. I plugged the relevant (small diameter) hoses with a piece
of paper towel as I removed them and made sure the opening was sitting
as high up in the engine bay as possible. I lost maybe a tablespoon of
coolant.

Re: 1991 Accord Idle control
My guess is that I can remove the three bolts mounting the IAC assembly to
the manifold. But what next, what is there to clean? How do I clean this?
Use somekind of solvant?

Pull the 3 bolts and leave the hoses connected. Just pull the unit away from
the intake (won't give you much room to work with it). I used a spray carb
cleaner, like Berryman's.
