Zusammenfassung:	A method for operating an internal combustion engine in particular an Otto engine, having continuous lambda control 12 and having an idling controller 10. From the lambda control 12 an additional square wave signal of low amplitude in the form of a forced amplitude is added to a desired injection quantity of the internal combustion engine. If the revolution rate deviates from a desired value, the idling controller 10 outputs an output signal for altering advance of the ignition timing to compensate for the deviation. In so doing the forced amplitude of the lambda control 12 is added 18 to the output of the idling controller 10 for the advance angle intervention. Prior to addition 18 of the forced amplitude of the lambda control 12 to the output of the idling controller10 , the forced amplitude may be multiplied 16 by a predetermined gain value.
