Your engine depends on the right air-fuel mix to run smoothly, and the Civic IAC (idle air control) valve controls the air entering the engine to ensure an accurate mix. The main cause of faulty IAC valves is clogging from carbon, dirt and other debris which restrict airflow, resulting in decreased RPMs, and restricted airflow leads to excess fuel in the engine, which causes backfiring through the tail pipe.
