Idle Speed and Mixture Adjustments


Idle speed and mixture for both of the engines covered by this guide is electronically controlled by the computerized fuel injection system. Adjustments are neither necessary nor possible. All threaded throttle stop adjusters are factory set and capped to discourage any tampering; in some areas, tampering is illegal. In most cases, proper diagnosis and parts replacement will correct any such problems.
