Abstract
A method and a system for adjusting a base idle speed of an engine are described. In one example, the method reduces engine speed according to output of a sensor that senses mechanical vibrations. Once a vibration level exceeds a threshold, engine speed reduction ceases and the base engine idle speed is adjusted according to a present engine speed.
