What will happen if the car throttle is too dirty and not cleaned?

An unclean throttle will also cause air with impurities to enter the combustion chamber of the engine. Both of these results will lead to abnormal engine operation, mainly manifested in unstable idle speed, sudden feeling of accelerator stepping off during driving, reduced power, even difficult starting and increased fuel consumption.

After the automobile throttle body is dirty, its influence is various. According to the design principles of different models, the comprehensive consequences mainly include:

1, affecting vehicle starting: unable to start or difficult to start.

2. Abnormal idle speed: unstable idle speed, driving (too high or too low idle speed), etc.

3. Fuel economy is affected: fuel consumption may increase.

4. Affect other parameter values: for example, the throttle opening and stepping motor steps collected by ECU will be affected, resulting in errors, such as ignition advance, injection timing and injection quantity. In this way, the engine has many shortcomings, such as poor working conditions, rising fuel consumption and engine jitter.

5. Unable to accelerate and speed up: for example, the throttle is stuck.

6, emissions are not up to standard.

7, car, hair and other anomalies.

8. Obstruction during refueling: For example, the throttle body is stuck and the idle valve cannot turn.

9. Other anomalies: The possibility of other faults is not ruled out, and it should be determined according to environmental emission standards (European standards) and vehicle models.

When the throttle is found to be too dirty or other abnormal, it should be suggested to send it to after-sales service for maintenance and troubleshooting in time to restore the original performance of the vehicle. (Photo/Text/Photo: Chen Miaoling) @20 19
