The speed of BYD g5 refueling engine is about 1200 rpm, and the refueling response is slow. What happened?

Hello, the car needs maintenance. Obviously, the ignition energy has dropped. Clean the carbon deposit on the throttle. Check whether the data flow of the throttle position sensor is normal, and replace the spark plug and air filter. Check whether the air flow signal is normal, etc. Go to the store for inspection and maintenance in time to ensure comfortable and stable driving. Thank you. There is something wrong with the car, find the car master. 4S shop professional technician, 10 minutes to solve.
