A method for operating an internal combustion engine having a first fuel injection system for injecting fuel into a combustion chamber of a cylinder of the internal combustion engine, and having a second fuel injection system for intake manifold injection, an injected fuel mass being corrected for the adaptation of an air/fuel mixture ratio; and at least one first adaptation value for the first fuel injection system being used and at least one second adaptation value for the second fuel injection system being used. The first and the second adaptation value are evaluated in order to conclude whether there is an error in an air system of the internal combustion engine.
