How often should the electronic throttle be replaced?

The electronic throttle does not specify the replacement cycle, and it needs to be replaced only if it is damaged. The damaged throttle will cause the vehicle to fail to start, the exhaust pipe emits black smoke, the idle speed is high, and the acceleration is not smooth, so it needs to be replaced in time. Throttle fault performance is as follows:

1, the engine idle speed is unstable, the idle speed continues to decrease, and it is difficult to start the engine, which is the difficulty of cold start;

2, the engine idle speed instability or no idle speed;

3. The engine is difficult to start;

4. The engine has insufficient power, poor acceleration performance and unstable operation.
