Does the spark plug throttle need cleaning?

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.
