What are the manifestations of throttle carbon deposition?

If you accelerate slowly when driving, get angry quickly. When it is difficult to start a cold, the valve of your car is likely to accumulate carbon. Generally speaking, if the car engine is carbon-deposited, it will obviously feel the jitter of the car engine when idling, obviously lack of power when accelerating, and poor ignition in severe cases. The symptoms of automobile valve lift mainly include abnormal engine jitter, sudden increase of engine speed at idle speed, increase of fuel consumption, decrease of power and difficulty in starting. The following specific analysis: 1, abnormal engine jitter. Excessive valve lift will affect the fuel delivery and ignition of the engine, resulting in abnormal combustion of fuel and mixture, abnormal engine operation and engine jitter. 2. Idle speed suddenly rises and falls: due to excessive carbon deposition in the valve of the car and poor fuel delivery, the engine speed will also rise and fall suddenly when the car is idling; 3. Increased fuel consumption: too much carbon deposit on the valve of the car leads to the fuel in the engine not being fully utilized, resulting in fuel waste, thus increasing the fuel consumption of the car; 4. Power drop: if the vehicle has problems such as power drop and poor fuel supply, it is mostly caused by carbon deposition on the throttle of the vehicle; 5. Difficulties in starting: There are many reasons for the difficulty in starting a car, including excessive carbon deposition on the valve of the car, failure of the spark plug, and lack of fuel. The specific situation will be further investigated in detail.
