Methods and systems are provided for purging condensate from a charge air cooler to an engine intake. During an engine deceleration event, the vehicle is downshifted into a lower gear to increase RPM and airflow through a charge air cooler to purge stored condensate to the engine intake. By delivering condensate while an engine is not fueled, misfire events resulting from ingestion of water are reduced.
