A control device for an engine including an EGR system, the control device includes an electronic control unit. The electronic control unit is configured to forcedly open and close an EGR valve and make a malfunction diagnosis of the EGR system, during fuel cutoff, perform ignition timing retard control when the engine returns from the fuel cutoff, and set the ignition timing at a start point of the ignition timing retard control to a more advanced value when an elapsed period from the malfunction diagnosis of the EGR system to a return from the fuel cutoff is short, as compared with the case where the elapsed period is long, so as to reduce a retard amount of the ignition timing at the start point of the ignition timing retard control, relative to the ignition timing immediately before the start of the ignition timing retard control. |
