*: Check the "Fuel Cut Elps Time" value in the Data List or the freeze frame data which were present when the malfunction occurred. If the value is more than 0 seconds, a high engine speed (fuel cut speed +500 rpm or more) has occurred in the past. Since the misfire may be caused by valve rocker arm detaching due to an extremely high engine speed, check that the valve rocker arms are properly attached Removal. By clearing the DTC, "Fuel Cut Elps Time" will be cleared.
