What are the effects of a dirty throttle body?

[Tyrone]

A dirty throttle body can affect the starting performance of the vehicle. Below are the specific impacts of a dirty throttle body: 1. Affects vehicle starting: Difficulty in starting. 2. Affects the idle condition of the vehicle: Unstable idle speed, either too high or too low. 3. Impacts fuel consumption: There is a possibility of increased fuel consumption. 4. Affects other parameter values: Such as the throttle opening and the number of steps of the stepper motor collected by the ECU, leading to incorrect adjustments like ignition timing, fuel injection timing, and fuel injection quantity. This can result in poor engine performance, increased fuel consumption, engine shaking, and other adverse conditions. 5. Weak acceleration and poor throttle response, such as throttle sticking. 6. Other faults cannot be ruled out. The specific impact should be determined based on the environmental emission standards (e.g., Euro standards) and the vehicle model. If the throttle body is excessively dirty or shows other abnormalities, it is recommended to send it for after-sales inspection and repair promptly to resolve the issue.
