Methods and systems are provided for increasing a catalyst temperature prior to entering a vehicle mode where combustion is temporarily discontinued. In one example, a method for increasing a temperature of an emission control device before a transient fuel shut-off (TFSO) event of an engine via a spark timing adjustment and an exhaust valve opening timing adjustments. Adjustments of the spark timing and the exhaust valve opening timing may change depending on whether a transient fuel shut off event of an auto-stop event occurs.
