Information is provided for the do-it-yourself car owner on servicing the exhaust gas recirculation (EGR) system, the main exhaust emission control used by manufacturers since 1973. The EGR system may possibly be the cause of the following problems: rough engine idle, rough engine performance during light-throttle acceleration, a deep sag in engine speed with acceleration, engine stalling on deceleration, and engine pinging. The EGR system's function is to control nitrogen oxides by reducing combustion temperature; this is done by introducing exhaust gas into the intake manifold through a control valve to lower the temperature. Step-by-step instructions (and illustrations) are provided for servicing the American Motors', Chrysler, Datsun, and Ford EGR systems, excluding electronic systems.
