With the engine fully warmed up, check VOLTAGE at the Green/red wire. It should read exactly 1.000 volts. If not, turn the screw until it reads 1.000v. Snap the throttle a few times, recheck, readjust until it consistently reads 1.000v at idle, fully warm.

That writeup is fine, but I'd change one thing. Over time, wires and connectors age. Ideally, I like to go to the ECU to check voltages, but I know some people are scared of pulling the carpet back a little and backprobing the ECU. The best reading (not at the ecu) can be obtained by checking voltage at the green/red wire. 1 volt (on the nose) is what you're looking for. 1k ohm will work, but like I said, if there are other resistances in the circuit (like 20+ year-old wiring will have) you won't get the most accurate reading. This is why whenever possible, check voltages, not resistances. Sadly, the FSM was pretty much written for resistance values
