1. Aging of engine parts;Car shaking is also related to the aging of the engine foot (also known as the claw pad). The engine foot is actually the shock absorption system of the engine. The engine foot is responsible for absorbing the slight shaking of the engine during operation. If there is a problem with the engine foot, these vibrations will be transmitted to the steering wheel and the cab, causing jitter when idling.
2. The main reason for idling unstable jitter: serious engine carbon accumulation: cars always have the problem of carbon accumulation, including cylinder carbonization, throttle carbonisation, spark plug carbonization, intake carbonisation, etc.
3. The main reason for idling jitter; the most common cause of car jitter is that the throttle valve is too dirty or the fuel injector has too much carbon.
4. The most common cause of idling jitter is excessive carbon accumulation in the throttle valve or fuel injector nozzle. When there is too much carbon inside the engine, the cold starts.The gasoline ejected by the fuel injector when moving will be absorbed by a large amount of carbon, resulting in excessive thinning of the mixed gas, making it difficult to start. In this case, it is easy to start the car only when the gasoline absorbed by the carbon is saturated.
5. The most common reason for car jitter may be excessive dirt on the throttle and too much carbon accumulation in the fuel injector.
1. Solution: Clean the oil road and check whether the idling motor has carbon accumulation that should be cleaned. 2. One of the reasons for the jitter caused by the ignition system problem is the poor operation of spark plugs, high-voltage wires and ignition coils. Solution: Check whether the spark plug has too much carbon and replace the spark plug.
2. The common solutions to body shaking are as follows:It can be solved by doing tire dynamic balance. When doing dynamic balance, check whether the tire hub is deformed. Go to the repair shop for inspection and repair according to the actual cause of the failure. The main reasons for car shaking are as follows: the engine has serious carbonisation. Spark plugs accumulate carbon.
3. Idling shaking After driving our car for several years, there is often idling shaking. The main faults are that the idle speed is high and low, and the engine speed is irregular. The reason is generally caused by the throttle valve is too dirty or the fuel injector.
4. Solution: Check whether the spark plug has too much carbon and replace the spark plug. Unstable oil pressure: It is recommended to go to the 4S store to check whether the fuel supply pressure and the intake pressure sensor are normal. If the oil supply pressure of the oil pump is abnormal or the numerical error and poor operation of the intake pressure sensor, it will cause the body to shake.
5. Solution; the best way is to clean the oil line and clean it regularly. The use of PNF original liquid fuel additives can solve the above problems caused by carbon accumulation.
6. Solution: replace the ignition coil, replace the foot glue, replace the spark plug, replace the intake pressure sensor, replace the air filter and clean or replace the fuel injector.
Too much carbon accumulation; if the carbon accumulation in the engine cylinder is serious, it will cause spark plug blockage and valve blockage, which directly leads to the shaking of the car when idling.
Engine parts are aging. Car jitter is also related to the aging of engine parts. At this time, if there is a problem with the engine parts, these vibrations will be transmitted to the steering wheel and the cab, causing jitter when idling.Solution: Replace auto parts. The engine has serious carbonization.
The engine has serious carbon accumulation. The most common cause of car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon. Ignition system problems. You should check the working condition of spark plugs, high-voltage wires and ignition coils. If the ignition system is not working well and the spark plug jumps well, it will also lead to such faults. The oil pressure is unstable.
The most common reason for car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon.
Let the engine idle, hang the low gear, and slowly release the clutch pedal And increase the accelerator to start. If the car body shakes obviously, it means that the clutch is shaking. The positive pressure between the main and passive discs is unevenly distributed.
The reason why the clutch foot shakes unconsciously is that there is no place to bear the weight of the foot. Step on the clutch with your front foot: Don't leave the car with your heel. Check the driving posture: make sure that your feet can be placed naturally on the pedals, and there is enough room for your knees to move. It may be that the seat is too far from the foot, causing the clutch to be too far from the foot to step on.
Analyze the problem: This problem usually occurs because the rigidity of the body is not enough, resulting in the deformation of the vehicle during driving, the friction or shaking of the door and the frame, or the friction between the steel plates caused by dewelding in some places.
Because there is no way for the engine to make corresponding changes according to the spark plug of 0.8 gap for a moment, it will shake. It's like two people with different personalities, in order to be together. One of them always has to make changes for his partner to adapt to his partner's shortcomings and keep up with his partner's rhythm.
There is also an ignition system. The ignition high-voltage line generally rarely has problems. So the main problem is in the ignition coil and spark plug, because they are all consumable parts. When the performance of the spark plug declines or the use of inferior spark plugs, it will lead to weak acceleration, acceleration jitter and other conditions.
Some veteran drivers may think that the more fuel you add to the vehicle, the more expensive it is. In fact, adding too much oil will not only increase the internal resistance of the engine, but also easily cause the engine to accumulate carbon, and in serious cases, it will burn oil.
The possible reasons for the car's shaking like a twitch are as follows: the fuel injector and throttle valve have serious carbon accumulation, or the throttle valve is too dirty, which is the car's shaking for no reason, the most common The phenomenon seen.
The most common reason for car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon.
For this kind of fault performance, it is recommended to check the following fault causes:First, the vibration or weak acceleration caused by the carbonization of the vehicle engine. In this case, it is recommended to clean the carbon accumulation of the throttle valve and the intake channel, and then check the carbon accumulation in the cylinder and whether the carbon accumulation of the valve base is serious.
The reasons for the serious acceleration jitter of the car are the dirty air filter, the unstable concentration of the mixed gas caused by unstable oil pressure, and the ignition system of the engine. The air filter is too dirty: The air filter is to protect the engine from foreign matter or dust. Let the clean air flow into the engine.
1. [Pacific Automobile Network] Seven major reasons for car jitter: engine cylinder shortage, aging or looseness of foot glue, ignition system problems, unstable oil pressure, dirty air filter, The high-voltage line is broken and the fuel injector is blocked.
2. Why does the vehicle shake? The engine lacks cylinder and lacks fire. At present, mainstream family cars are all four-cylinder engines. Its biggest feature is low noise and strong stability. However, if a cylinder does not work properly, it will affect the other three cylinders, resulting in obvious jittering of the engine.
3. Solution: Check whether the spark plug has too much carbon and replace the spark plug.
4. Causes and solutions of body shaking. The aging of engine parts and car shaking are also related to the aging of engine parts. At this time, if there is a problem with the engine parts, these vibrations will be transmitted to the steering wheel and the cab, causing jitter when idling. Solution: Replace auto parts.
5. Idling shake. After driving our car for several years, we often have idling shake.In the case of movement, the main fault performance is that the idle speed is high and low, and the engine speed is irregular. The reason for this is generally caused by the dirty throttle valve or too much carbon accumulation in the fuel injector.
