Reset 88 Fox body PCM/Computer after replacing the IAC?

[The needs of the many]

Hello. Idler Air control valve giving me fits- car starts, runs fine for a block or two- computer leans out fuel mixture, and IAC fails to adjust? What is the voltage at the IAC connector supposed to be? Took my IAC apart and gave it a good cleaning. From what I understand, you can't just bolt it back on, you have to reset/relearn any new sensor...disconnect the battery using a jumper, or simply disconnect and turn on the headlights? Really wish I could get some data online but it's just not available.
Any clairification would be great.

I have cleaned mine and just installed with no issues.

Any codes?

IAC works on PWM so no set voltage to measure

Perform the base idle reset procedure. Give it a few drive cycles and then dump codes. Also, have you opened up the ECU and inspected the capacitors?
