Abstract
Methods and systems to determine a presence or absence of engine misfire or spark plug fouling are presented. In one example, rates of change in engine speed are arranged in engine data blocks and root mean square values for the rates of change in engine speed are determined. The presence or absence of engine misfire or spark plug fouling may be based at least in part on the root mean square values.
