So the first thing to check if you haven't service any Idle speed areas, would be the engine grounds and harness conectors. clean corrosion, and apply di-eleictric grease to connectors
The second area to check is an Idle adjsutment screw directly behind the IAC solenoid. It is large, and on the left side as you are looking at the SPFI unit. The passageway gets carboned up, you should take out that screw and remove the IAC housing (four screws) and use some seafoam/etc to clean out the carbon. Then you can use that screw for fine idle adjustments. It is a small needle valve, so not much air passes through it.
There is no adjustment on the IAC solenoid itself, like there is with GM style IAC's. The actual plunger and sprin is built into the small IAC housing assembly on the front of the TBI, and not on the IAC solenoid itself.
