May I ask the master, my car has a gas pedal, the car shakes and hurts, and it is normal not to incr

Hello, this situation may be the reason why the throttle is too large, you can go to the 4S shop to clean the throttle, clean the fuel injector, and check the ignition performance of the spark plug.

Hello, this situation may be the vehicle engine has a missing cylinder fault, it is best to go to the repair shop to find a repairman to use the computer to read the fault code of the engine, check whether there is a missing cylinder fault.

Hello, if the engine idling is normal, the engine power is normal, and the gas throttle body shake may be a resonance caused by damage to the engine mount bushing or transmission bracket bushing, it is recommended to go to the repair shop to check it.

This situation may be caused by a problem with a spark plug, it is recommended that you check how well the spark plug burns first, and then replace the spark plug for testing. It may be the reason for the leakage of electricity in the ignition coil.

In this case, the key thing to check is whether the engine bracket is good, and the other thing is to check whether the drive shaft itself is normal. Another aspect is to check whether there is any oil leakage in the drive shaft? In addition, take a look at whether there is a lack of cylinders in the engine?

If this is the case for you, it is best to clean the throttle injector and replace the spark plug.

Generally speaking, because the engine has a lot of carbon deposits, it can be alleviated by cleaning the throttle or fuel injector.

Hello! What model is the vehicle, how large is the displacement, and how many kilometers has it traveled so far?

If this problem is this problem, it may be that there is some carbon accumulation on the bike, and it is best to find a professional person to test and repair it for you.

Analysis of the causes of car shake:

1. Cold start jitter.

First of all, starting from the cold start, the main reason for the cold start body shaking is that the fuel combustion is insufficient, resulting in insufficient power of the car. The ignition energy is low, and when starting, especially when the temperature of the fuel and lubricating oil is low, more oil is required to meet the power. Over time, the pole gap of the spark plug gradually increases, resulting in a decrease in ignition energy and poor fuel atomization, which leads to the shaking of the body.

In addition, the ignition energy can also be reduced due to the aging of the ignition coil, the aging of the high-voltage wire of the spark plug, or the leakage of electricity.

2. Suspension system problems.

Body shake is also related to the aging of the suspension system. It is mainly responsible for filtering out the shake of the engine when it is running, and if there is a problem with the suspension, these vibrations will be transmitted directly to the steering wheel and cab, affecting the driving. When the engine is idling, it is easy to cause shaking when the electrical system in the car is turned on.

The engine will increase the load when the electrical appliances are turned on, causing the idle speed to drop, and to compensate for the jitter caused by the idle slip, the engine will automatically increase the speed by partially. So, when the electrical system, especially the air conditioner, is turned on, the engine will often shake. This jitter is likely to be caused by the aging of the shock absorber and needs to be replaced in time.

3. Tire problems.

For tires, the tire balance must be done once when the car is replaced with new tires and new steel orange rotten rings, otherwise the steering wheel is prone to shake when the counterweight is uneven. If you find that the tire weight is uneven, you need to add lead to the inside of the steel rim and carefully average the weight of the tires on both sides. Whether it is a general steel ring or a lightweight aluminum ring, it may deform or crack when subjected to a certain external force.

Deformation of the rim can cause shaking when driving, uneven weight of the rim can also cause shaking when driving, and incorrect angle of the rim can also cause shaking when driving.

4. Throttle problems.

The most common cause of car shake may be a dirty throttle valve and excessive carbon build-up in the fuel injector. After the car travels for a period of kilometers, the circular throttle valve will cause the throttle to close poorly or the idle motor to stagnate because it is too dirty, resulting in too high engine idling, and the carbon deposits generated by the engine in this process will also cause the vehicle to shake, especially when starting the vehicle, the engine will shake more than normal, and even sometimes it will not be able to start at one time. Therefore, when the body shakes, the first thing to do is to check the throttle and fuel injectors.

If you find that the throttle valve is too dirty or the fuel injector has too much carbon deposit, you should clean it with fuel injector cleaner or throttle cleaner in time.

5. The oil pressure is unstable.

If you still find that the body shakes after these are finished, it is recommended that you go to the repair shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is not normal, the intake pressure sensor is wrong and improper work will cause the body to shake.

1. It may be that the engine has a lack of cylinder or the high-voltage line is out of fire, which leads to acceleration jitter;

2. If the throttle is retracted at this time, the shake is reduced or disappears, and the speed of the vehicle changes with the degree of damage to the faulty parts when the fault occurs;

3. First, check whether the left and right half shafts are bent, and secondly, disassemble and check whether the inner walls of the left and right inner ball cages are worn and pits, which are caused by the parts of the inner wall of the inner ball cage that are often in contact with the outer skin of the needle roller bearing, that is, the parts that transmit torque (stress points), resulting in pits;

4. Because when the vehicle accelerates rapidly, due to the existence of a certain angle between the axial direction of the half axis and the axial direction of the inner cage, the force point continues to reciprocate along the axial direction during the rotation of the cage, and the force generated by this change spike continuously pushes the body to the right side of the left clan, so it leads to the phenomenon of shaking.

1. Under the action of long-term torsional fatigue and impact force, the half shaft of the car is prone to bending, twisting and breaking, as well as spline tooth wear or torsion, etc., which causes the car to accelerate again in a certain speed range, and the front of the car will have regular shaking, and the shaking will disappear or reduce after releasing the accelerator.

2. Since the car is on the gas pedal for a meal, then the problem is likely to be the engine operation, the engine needs to ensure that the work needs to have sufficient air, sufficient gasoline and a good ignition system, any problem will lead to the engine shaking.

3. As mentioned above, the engine needs to have enough air to ensure that it works, if the air intake system is leaking or blocked, then when the car is on the accelerator, there will be a situation where the speed shake cover is lifted.

4. In the engine ignition system, there are few problems with the ignition high-voltage line, so the main problems are in the ignition coil and spark plug, because they are all wearing parts, when the performance of the spark plug decreases or the use of inferior spark plugs will lead to the car acceleration weakness, acceleration jitter and other conditions.

5. The fuel system of the car is relatively large, and there are many parts, and if one of the components is abnormal or malfunctional, it will cause the engine of the car to shake during acceleration. For example, excessive carbon build-up on the throttle, faulty fuel injectors, faulty gasoline pumps, clogged gasoline filters, and so on.

Main causes of idle jitter:

1.Serious engine carbon deposits: Cars always have the problem of carbon deposits, including cylinder carbon deposits, throttle carbon deposits, spark plug carbon deposits, intake carbon deposits, etc.

When the engine has too much carbon deposit, it will affect the ignition energy, air intake efficiency and air-fuel ratio of the car, resulting in the unstable power output of the car, and the phenomenon of idle speed and acceleration jitter appears.

2.Unstable oil pressure: If you have cleaned the engine carbon deposits, cleaned the throttle, replaced the oil gasket and spark plug, etc.

And when idling, you still find that the body shakes, it is recommended that you go to the 4S shop to check whether the oil supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is abnormal, or the intake pressure sensor value is wrong, and the work is not good, it will cause the body to shake.

3.Engine cylinder shortage: Engine cylinder deficiency mainly refers to the engine one or more cylinders are not working properly, which is generally manifested as:

The exhaust gas flowing out of the car is obviously intermittent, and the exhaust pipe shakes violently, and the engine shakes clearly, sometimes accompanied by abnormal noises. This is mostly related to ignition coil failure.

4.Aging of engine parts: Shake in the car is also associated with the aging of the engine feet (also known as claw pads).

The engine foot is actually the shock absorber system of the engine. The engine feet are responsible for absorbing slight vibrations when the engine is running. If there is a problem with the engine base, these vibrations can be transmitted to the steering wheel and cab, causing vibrations at idle.

Solution; The best way is to clean the oil circuit, clean it regularly, and use PNF fuel additives to solve the above problems caused by carbon deposits. The fuel quality is not very good or the initial fuel of the new car is stored for too long, resulting in a rapid increase in the colloidal composition of the oil circuit, which will continue to pollute the fresh fuel and cause no good fuel to participate in combustion in the later stage, and the carbon deposition exceeds the standard, which is especially common for China VI vehicles. We can only gradually alleviate most of the problems by maintaining clean oil circuits.

The reasons why the car fuel gauge does not move are roughly divided into four categories, 1. The plug of the oil level sensor falls off, and the oil level sensor is what we often call the oil float. 2. The battery power of the car is too low. 3. Lack of lubrication of the fuel gauge pointer. 4. There is a problem with the fuel gauge line.

When the oil meter does not move, there are corresponding solutions, first of all, the best is to go to a professional maintenance organization for problem inspection and repair. Secondly, if the situation is urgent, we can also solve it by ourselves, if the oil float falls off, we only need to plug it back in; If the battery is out of power, we need to charge the battery immediately to avoid unnecessary trouble; Finally, you can check the fuel gauge pointer, if there is a lack of lubrication, apply lubricating oil to the oil gauge pointer.

2.If the throttle is closed at this time, the jitter will decrease or disappear, and the speed of the vehicle will change with the degree of damage to the faulty part when the fault occurs;

3.In most cases, this is caused by pitting at the point where the inner wall of the inner cage is often in contact with the outer skin of the needle roller bearing, i.e. where the torque is transmitted (stress point). So first, check if the left and right half shafts are bent.

Secondly, disassemble and check whether there is wear and pitting on the inner walls of the left and right inner cages.

When the vehicle accelerates rapidly, because there is a certain angle between the axial direction of the half shaft and the axial direction of the inner cage, in the process of cage rotation, the stress point constantly changes back and forth along the axial direction, and the force generated by this change continuously pushes the body to the left and right sides, thereby causing the phenomenon of shaking. Under the action of long-term torsional fatigue and impact force, the half shaft of the automobile is prone to bending, torsion and breakage, and its spline teeth are worn or twisted, resulting in the acceleration of the car to a certain speed range, the front of the car shakes regularly, and the shake disappears or decreases after the accelerator is released.

The problem is most likely with the engine running. If the engine needs to work, it must have enough air gas, enough gasoline and an ignition system in good working order. On the one hand, any problem can cause the engine to shake.

As mentioned above, the engine must have enough air gas to ensure its operation. If the air intake system leaks or becomes clogged, there will be acceleration jitter when the car is refueled. In an engine ignition system, there are usually very few problems with the ignition finger hole high-voltage wire, so the main problems are the ignition coil and spark plug.

Because they are all consumable parts, when the performance of the spark plug is reduced or when an inferior spark plug is used, the car will not be able to accelerate the jitter. The fuel system of the car is relatively large, and there are many parts, and the abnormality or failure of one of the components will cause the car engine to shake when accelerating. For example, excessive carbon build-up on the throttle, faulty injectors, faulty gasoline pumps, clogged gasoline filters, and so on.

In general, body shaking is not a trivial matter. Unless it is a normal frustration, you should go to a professional repair shop or 4S shop for repairs immediately.

The problem began when the car was bought and ran more than 2,000 kilometers. When the throttle is refueled, the car starts to shake (stutter).I went to a repair station, and the other party said that there was no problem with the inspection, but the gasoline was not good. It is recommended to add 97 gasoline several times.

No problem. But as it was told, the problem was not solved. I had to change to a more famous special maintenance station.

The other party's preliminary inspection said that the computer showed that there was no problem with the engine. The old master was not there, and asked to come back another day. Everything that should have been replaced was replaced, but it was disappointing that the problem was not solved.

The car is also required to be parked at the garage. After the check, the decision is made. Ask an expert to help, can you help us consumers!

A] When you refuel, the vehicle starts shaking. This concept and phenomenon is very vague and can only be used to analyze closely related systems, and it is necessary to determine whether the engine shake is causing the shake of the vehicle or the shake of the vehicle itself.

If the engine shakes the vehicle due to the shake, it is recommended to check the engine.

Fuel supply system and ignition system.

The fuel supply system can test the fuel supply pressure of the fuel pump by refueling the engine urgently, and confirm whether there will be insufficient fuel supply pressure and engine shaking during emergency refueling.

If there is a problem with the ignition system, you can test the ignition voltage and ignition time with a special tool to confirm whether the engine shakes due to the poor operation of the ignition system.
