A method for controlling an internal combustion engine of a motor vehicle. The method includes the use of an electronic control device for controlling the internal combustion engine in a motor vehicle, an irregular running determination unit for fault recognition, an injection quantity correction unit, a lambda probe associated with a defined group of cylinders, the injection quantity of a cylinder to be investigated of the defined group is adjusted in the direction of lean by a differential adjustment value associated with an irregular running differential value, and the injection value of at least one of the remaining cylinders, which are associated with the same lambda probe, is correspondingly adjusted in the direction of rich, so that in total a predetermined lambda value of this group of at least approximately 1 is reached.
