Ford Contour/Mystique/Cougar 1995-1999 Repair Guide

Idle Speed and Mixture Adjustments


The engines covered by this guide utilize sophisticated Sequential Fuel Injection (SFI) systems in which an engine control computer utilizes information from various sensors to control idle speed and air/fuel mixtures. No periodic adjustments are either necessary or possible on these systems. If a problem is suspected, please refer to Driveability & Emissions Controls in this repair guide for more information on electronic engine controls and fuel injection.
