Does the Car Throttle Need Cleaning?

[EzraLee]

Car throttle is a controllable valve that regulates air intake into the engine. There is no strict requirement for the cleaning frequency of the throttle, but the specific conditions are as follows: 1. Typically, 4S shops recommend cleaning the throttle around every 20,000 kilometers. Different car models have different conditions; some vehicles' throttles get dirty easily and may require cleaning as early as 7,000 to 8,000 kilometers. 2. When symptoms like unstable idling occur, cleaning should be considered. If the engine makes unusual noises or has noticeable vibrations when starting the car, it indicates severe throttle clogging, requiring immediate cleaning. The hazards of not cleaning the throttle in time are as follows: Prolonged neglect can lead to throttle opening errors and allow impurities into the engine combustion chamber, both of which can cause abnormal engine performance. This mainly manifests as unstable idling, sudden loss of throttle response while driving, reduced power, and in severe cases, difficulty starting the engine and increased fuel consumption.
