The reason why Jing Rui's throttle doesn't work

The reason for the fracture of throttle body may be mechanical failure or dirt and improper adjustment. 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 drop, and it is difficult to start the engine. This is the difficulty of 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.

Precautions:

Some cars are easy to stall when idling, and only when the driver keeps stepping on the accelerator can they not stall, so this is the phenomenon of not idling. Serious carbon deposition on the throttle may also lead to unstable idle speed, and it is necessary to clean up the carbon deposition after this problem occurs. When cleaning the carbon deposit, it is necessary to remove the throttle first, and then clean it with a professional cleaning agent. It needs to be wiped with a special cloth after cleaning.

After the carbon deposit is cleaned and put back, it is best to re-match the ecu, otherwise it may increase fuel consumption. Don't add inferior gasoline to the car at ordinary times, which will aggravate the carbon deposition in the throttle or cylinder. Some in-cylinder direct injection engines are very prone to carbon deposition. It is suggested that the owners of in-cylinder direct injection engines clean up the carbon deposits every 20,000 kilometers. A better method to remove carbon deposits is walnut sand cleaning.
