Tiida cleaned the accelerator in 2008, and the car couldn't stop.

If you find that the 2008 Tiida vehicle does not operate normally after cleaning the accelerator, please consider the following possible reasons:

1. Improper cleaning: If the throttle valve is operated improperly or the cleaning agent is used improperly, the throttle valve may not be closed or opened normally. In this case, it is recommended that you check the cleaning process again and make sure to use proper cleaning methods and products.

2. Throttle failure: During the cleaning process, the throttle may not work normally because the cleaning agent penetrates into small parts or the valve is damaged. This may require inspection and repair of the throttle valve to restore its normal function. It is recommended that you send your vehicle to a professional garage or dealer for diagnosis and maintenance.

3. Contact problem: After cleaning the accelerator, if the relevant sensors, pipelines or wires are not installed or connected correctly during reassembly, the vehicle may also run abnormally. Please check whether there are any contact problems during cleaning and ensure that the relevant components are installed and connected correctly.

4. Other problems: Abnormal vehicle operation may be related to other components or systems, such as unbalanced air-fuel ratio, sensor failure or other mechanical problems. If the vehicle cannot run stably, it is recommended that you consult professional automobile maintenance personnel for comprehensive diagnosis and maintenance.

No matter what happens, in order to ensure safety and reliability, it is recommended to send the vehicle to a professional garage for inspection and maintenance as soon as possible. They will provide appropriate solutions according to the specific situation.
