YOU CAN'T. It is not adjustable and is NOT to be tampered with. VERY important to leave it alone.You have another problem with the engine sensors if it is idleing to fast are to slow. Is the check engine light on ? If it is you need to have the engine SCANNED with an engine scanner.Check for vacuum leak that will cause it to idle to fast. TPS/ Throttle position sensor may be bad too.
