Subject: repairing the idle stabilizer unit
Content-Type: text/plain; charset=us-ascii
Mike and Matthew,
Idle stabilizer unit does not seem a
likely cause of this problem. It is easy to swap out
but I think I would look elseware for the problem.
This relay is involved in stabilizing rpm while under
a ac looad or steering I think. How does the van run
if you just pull the single wire to the o2 sensor?
Have you changed the temp2 sensor? regards gary

Matthew,
Not sure that you can always repair them but
If
you have the time you might pop open the relay and
try
cleaning the contacts of the relay itself. Look
for
something like pitted points. If it is the
electromagnetic coil, give it the sniff test and
pitch
it if it is not working and smells bad. How does
the
relay appear bad to you? gary

Gary -
Matthew and I have been talking about mine. It starts
fine and runs ok
on
the highway, but once it's warm, the idle wavers a bit
around 8-900
rpm,
then the engine seems to quit for a second, and picks
back up. Once in
awhile, when it pick back up, the idle jumps to about
1200 rpm and
then
subsides back to 8-900.
I've tried two ECUs with identical results. I tried
running with the
idle
stabilizer valve (on top of the engine) disconnected,
but no change, so
I'm
suspicious of the idle stablilizer relay (by the
taillight).
My digitool doesn't show any odd readings for the AFM
or Temp II
sensor.
The O2 sensor is bouncing around like normal, although
it does seem to
be
spending more time below .5 than above.
If we had a better place to work I would see if
Matthew and I could
swap
units, but working outside in the dark is not too
attractive right now.
Maybe over Christmas I can open mine up and see what
it looks like.
Anything else that could be causing those symptoms?
Is this a problem
that's likely to strand me someplace, or just make
running around town
a
problem?
