Why does my 2010 Hyundai Accent keep backfiring? on 2010 Hyundai Accent

Check engine light kept coming on and when the vehicle is taken in, the technician cannot find a problem (typical). The vehicle has been taken to a Hyundai dealership for the same problem more than three times. The last time a coil was changed, the check engine light does not come on anymore, but the car continues to backfire.
