Can the Throttle Body Be Left Unclean Indefinitely?

[Ricky]

If the throttle body is never cleaned, it will affect the engine's air intake, leading to increased fuel consumption and reduced power. Therefore, it is recommended to clean the throttle body regularly. Over time, carbon deposits will accumulate on the throttle plate, but cleaning the throttle body is relatively simple and does not necessarily take much time. Below are the hazards of not cleaning the throttle body: 1. Prolonged neglect of cleaning can cause errors in the throttle opening angle. 2. It can also allow air with impurities to enter the engine combustion chamber. Both of these outcomes can lead to abnormal engine operation, mainly manifested as unstable idling, sudden throttle cut-off sensations while driving, reduced power, and in severe cases, even difficulty starting the engine and increased fuel consumption.
