I feel that the fuel consumption is a bit high, more than 30 thousand kilometers. Do you want to clean the throttle and match it? Do you want to change the spark plug?

According to your description, your car has traveled 3W kilometers. I suggest you clean the throttle. After cleaning the throttle, you need to match it. Spark plugs also need to be replaced. Generally, ordinary spark plugs used in the original factory need to be replaced. Generally, ordinary spark plugs are around 3 km. There are two types of fuel filters. If it is for external use, it needs to be replaced every 2 weeks or so. You have been driving for 3 kilometers, so it is recommended to replace it. If it is a built-in fuel filter, it does not need to be replaced. Generally, the built-in fuel filter is about 10W km. Throttle matching needs a special computer to match. I suggest you go to the 4S shop to clean it.
