Idle adjustment

Would someone know how the idle speed is controlled. The manual I use shows a slightly different CFI injector module. Mine has two gears meshed with a small adjustment screw in a fairly inaccessible position. I have now set it so that the adjustment stops the ISC motor lowering the speed, but the engine seems to be able to run slower at times. The computer must control the injectors at idle along with the ISC. Is an explanation available somewhere online? A mechanic said that I should reset the computer with a jumper lead and would then have a very short time to adjust the speed before the computer took control again. That is different from the instructions in the manual.
How is that done?
I do not use the car often, and it runs OK so it is not worth trying to get it right as soon as possible.
