What Causes Idle Vibration After Throttle Body Cleaning?

[JasonRose]

Cleaning the throttle body can cause idle vibration if the data is not properly matched. After cleaning the throttle body, it is necessary to reset the ECU or disconnect the negative terminal of the battery to allow the throttle to reset. The throttle body is a controllable valve that regulates the amount of air entering the engine. The air mixes with fuel in the intake manifold to form a combustible mixture, which then ignites to produce power. The throttle body is connected to the air filter at the top and the engine block at the bottom, often referred to as the "throat" of the engine. The throttle opening controls the air intake, and the intake manifold contains an air flow sensor that measures the amount of incoming air. The ECU uses this data to adjust the fuel injection volume. The air flow sensor detects changes in airflow, and the ECU adjusts the fuel injection accordingly to achieve optimal combustion efficiency. The throttle position sensor monitors the throttle opening and matches it with the air flow sensor data to regulate the ideal air intake. If the throttle body is dirty, the throttle opening must be increased to ensure proper air intake matching. This relative opening value is stored in the vehicle's ECU.
