90q rough idle when warm?

[Marc Swanson]

I have another question for the lists (this one not transmission related at
least)....

My 1988 90q starts up and idles just fine.  After a little while as the
engine begins to warm up, the idle starts to "hunt" between about 1100 and
800.  I checked the O2 sensor and it appears to be working fine.  The only
temperature related device that I know isn't working is the dreaded
multifunction sensor.  Would that have an effect on the running of the
engine or just the coolant gauge and AC related stuff?  I also ran an output
test and all of the devices seem to work fine (at least they click/clack
anyway).  Any other possible suspects?

Thanks
