Abstract

A method for a combustion engine (200) of a vehicle is presented. The combustion engine comprises: - a first group (225a) of two or more cylinders (220a-d) connected to a first exhaust gas manifold (240a) comprising a first pressure sensor (241a); and - a second group (225b) of two or more cylinders connected to a second exhaust gas manifold (240b) comprising a second pressure sensor (241b). The method performed during normal operation of the combustion engine comprises: - inducing at least one fuel cutoff for at least one (220a) of the four or more cylinders (220a-h); - measuring at least one first and at least one second misfire pressure responses by utilization of the first and second pressure sensors, respectively; - determining at least one misfire template for the combustion engine individual based on the at least one first and the at least one second misfire pressure responses.
