ABSTRACT:
A system for maintaining engine air/fuel operation within the efficiency window of a catalytic converter. Fuel delivered to the engine is adjusted in response to a step change in an output of an exhaust gas oxygen sensor positioned upstream of the converter. The step change is shifted in response to an error signal derived from a downstream emissions sensor.
