I am sorry, but that is not true. You DO use the idle screw if you want to adjust the idle. Here are the proper steps:
- Disconnect the battery's negative for 30 minutes.
- Disconnect the plug going to your IAC
- Reconnect your battery's negative terminal.
- Start the engine, and set the idle to the rpm you want with the stop screw on the bottom of the throttle body.
Turn off the engine.
Reconnect the plug on the idle motor.
Make sure all accesories (radio, blower motor, a/c, lights, etc) are off and start the engine.
Let engine run for two minutes.
Turn engine off and wait two minutes then restart engine and let idle for two minutes with all accesories on.
If everything was done properly the computer should have learned it's new idle.
