Misfiring of cylinder 4, damages TWC (P0304)
Note

- Simultaneous misfiring at cylinders 4 and 10 usually indicates that the wrong seal has been installed between components M16/6 (Throttle valve actuator) and Intake manifold.To check, remove the air scoop at component M16/6 (Throttle valve actuator), press on component Throttle valve and check whether the seal is flush all around.In this case the gasket (oval version) must be replaced.
