Does the new car need to clean the throttle for half a year?

Don't make trouble. If nothing happens, don't do it. This is equivalent to repairing. If there is no carbon deposit, continue to use it. 15,000 to 20,000 kilometers If the engine is loud, the idling jitter increases, and the uphill refueling power decreases, then you can consider cleaning it. You should take it down and wash it. It's better not to open it than not to do it. If it is not cleaned, it will also cause three-way catalytic blockage. . . . get
