What are the symptoms of throttle failure?

1, the engine idle speed is unstable, and the high idle speed keeps decreasing, which makes it difficult to start the engine, especially the cold start.

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

It is difficult to start the engine.

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

5. The exhaust pipe of the car emits black smoke, which increases fuel consumption.

If the throttle is damaged, it needs to be replaced. Its general price is between 300-500, but the throttle of some vehicles is more expensive, and the price is between 600- 1000. The throttle to be replaced for each model is different, and the price will be different. The specific price will still be asked at the 4s shop.

Attention should be paid to the cleaning and prevention of throttle:

1, which should be dismantled and cleaned up.

2. Correct some misunderstandings of cleaning the throttle.

3. The fouling of the throttle is mainly engine oil vapor, followed by particles and moisture in the air. That is to say, using a qualified air filter and removing the crankcase ventilation pipe, the fouling speed of the throttle will be much slower.
