Continuing Idle Issue ... can not get down past 760 RPM w/ IAC disabled 200 1988

"7) Ignition advance ... ? ... My '88 has no vacuum line to the distributor for ignition advance. I thought this was managed by the Fuel ECU. ... Is there something else?"

There should be a vacuum line between the distributor and the ICU mounted on the WW fluid tank.

But I agree 760 rpm is what you should see, who knows how accurate a 25 year old tack is.
