How to Determine if the Throttle Body Needs Cleaning?

[LaHector]

Methods to determine if the throttle body needs cleaning: If symptoms such as slow acceleration, unstable idle speed, or decreased power occur, it may indicate that the throttle body is too dirty and requires cleaning. However, avoid cleaning the throttle body unless absolutely necessary; it can be done during major maintenance. The throttle body is a controllable valve that regulates air intake into the engine, available in two types: traditional cable-operated and electronic throttle bodies. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture for combustion and power generation. Connected to the air filter above and the engine block below, it is often referred to as the 'throat' of the car engine. In traditional engines, the throttle body operates via a cable or linkage, connecting the accelerator pedal to the throttle linkage plate. Electronic throttle bodies primarily use a throttle position sensor to adjust the throttle opening angle based on the engine's energy requirements, thereby regulating the air intake volume.
