Under What Circumstances Should the Throttle Body Be Replaced?

[SanAthena]

When the car's throttle body operates unsmoothly, frequently gets stuck, and subsequently causes issues such as failure to start, excessively high idle speed, or poor acceleration, it indicates that the throttle body cannot be repaired and must be replaced. The throttle body is located at the engine's air intake. Extended Information: I. Function of the Throttle Body: It controls the amount of air entering the engine. After the air enters the intake manifold, it mixes with gasoline to form a combustible mixture, which then burns to generate power. II. Precautions for Using the Throttle Body: 1. Regularly clean the throttle body. Excessive sludge buildup can lead to insufficient engine power and increased fuel consumption. 2. Apply oil to the fixed metal retaining ring before disassembly to prevent thread stripping. 3. After cleaning, maintaining the throttle body at its pre-cleaning opening can result in excessive air intake, causing engine shaking during startup and weak acceleration.
