What happens when the Volkswagen Lavida 1 4T accelerates after cornering?

The reason why the Volkswagen Lavida acceleration car will shake after turning is that the gear is too high, the speed is too low, and the speed can't bring such a high gear, just downshift.

Advantages: 1. The body is coordinated and durable, the standard configuration is relatively rich, and the riding space has certain advantages in the same level of cars, which is more comfortable;

2. The engine and transmission technology content is very advanced, the fuel consumption is low, the body is thick and safe, and the maintenance cycle is longer than that of other models, reaching 10,000 kilometers.

Disadvantages: 1. There is an abnormal sound in the door;

The speed of 3rd gear is slow, but the 4th gear is full of horsepower;

3. The window regulator has been replaced at 15,000 kilometers (indicating that the accessories are immature);

4. The reversing gear is sometimes tighter and not too handy;

5. The car is full of people and the air conditioner is turned on, and the engine power is obviously insufficient;

There is noise when shifting gears.

This was the case with my car before, and going to the 4S shop for inspection didn't solve the problem. Later, a friend recommended to me a fuel additive called all the way to the swish, the friend said that it was very easy to use, at first I didn't want to try, such a good car, I don't want to scrap the car because of a bottle of additives. He didn't believe it, so he added it in front of me on a business trip, and as soon as I drove, the car was really easy to drive.

When I went back, I added some to my car, and it really solved the problem of shaking. You can also try it. I'm not an insider, and I don't know how to maintain the car, so I can only use some maintenance products, hehe.

Hope it helps.

The most common reason for the serious carbon deposition of the engine causing the car to shake is that the throttle valve is too dirty or the fuel injector has too much carbon, because the gasoline adsorbed on the carbon deposit after the car is sucked into the cylinder by the engine for combustion, and the combustible mixture of the engine is dilute and thick, resulting in idle shaking after cold start. Solution: Siyoupu cleans the oil circuit and checks whether the idle motor has carbon deposits and should be cleaned.

Causes of jitter at idle:

1.The engine has serious carbon deposits.

The most common cause of car shake is a dirty throttle or excessive carbon build-up in the fuel injector. When the carbon deposit inside the engine is too much, the gasoline sprayed out by the cold start fuel injection head will be absorbed by the carbon deposit in large quantities, resulting in the mixture of cold start being too thin, making it difficult to start, in this case, only when the gasoline absorbed by the carbon deposit is saturated, it is easy to get on the car, and the gasoline adsorbed on the carbon deposit after the car will be sucked into the cylinder by the vacuum suction of the engine for combustion, and the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, causing idle shaking after cold start.

2.Problems with the ignition system.

Check the working condition of the spark plug, high-voltage wire and ignition coil, the ignition system and spark plug are not working well, and the poor working condition of the ignition system and spark plug will also lead to this kind of failure.

3.The oil pressure is unstable.

If you have cleaned the engine deposit, washed the throttle, changed the spark plug, etc., and still found that the body shakes when idling, it is recommended to check whether the fuel 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, the body shakes will be caused by abnormal oil pump supply pressure or wrong intake pressure sensor value and poor work.

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.

Analysis of the causes of the shaking of the gasoline version of the car:

1. 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.

2. Tire problems.

For tires, the tire must be balanced once when the car is replaced with new tires and new steel rims, otherwise the steering wheel will be prone to shake when the counterweight is uneven. If you find that the tire weight is not equal, you need to add lead to the inside of the rim to 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.

3. 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 throttle valve will be too dirty to cause the throttle to close loosely or the idle motor to stagnate, resulting in the engine idling speed is too high, 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 there will be a phenomenon that can not be started 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.

4. 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.

Hello! When the intake manifold or various valves leaks, the air intake volume of the engine is not right, which will cause the mixture to be too thick or too thin, and the engine will burn abnormally. This can cause the engine to shake at idle.

When the position of the air leak affects the vacuum level of the engine, the engine will shake violently, which has a greater impact on the idle speed of the cold car. Common causes are: air leakage caused by aging of the intake manifold mat, damage to the intake manifold or other parts grinding out of the intake manifold, vacuum tube plug falling off, ruptured exhaust gas recirculation EGR valve is not tightly closed, etc.

Excessive fouling of the throttle and intake. The excessive carbon and dirt deposits in the throttle valve and the surrounding air intake, and the change in the cross-sectional area of the air channel, make the control unit unable to accurately control the idle air intake, resulting in the mixture being too thick or too thin, and making the combustion abnormal. Common causes are:

The throttle has carbon deposits, and there are oil stains and carbon deposits in the air intake tract around the throttle.

Idle Air Actuator FailureIdle Air Actuator Failure Causes Inaccurate Idle Air Control. Common causes are: throttle motor damage or card issuance, throttle valve plate due to axle model carbon deposit, resulting in jamming.

The inaccurate air intake control unit receives the wrong air flow sensor signal and sends out the wrong command, which causes the engine idle air intake to be inaccurate, and the abnormal mixture concentration makes the engine burn abnormally, which is the indirect cause of idle instability. Common causes are: air flow meter or its line failure; Failure of the inlet pressure sensor or its wiring; Minchai engine control unit wiring harness contact is poor or the engine control unilateral side is faulty.

When the vehicle has an unstable idle speed, it is recommended to check the above components.

Hello, I suggest you clean the throttle and check the spark plugs.

The cause of "carbon deposition" should not be underestimated, which will cause insufficient combustion of gasoline and cause the engine to shake. The impact of engine carbon deposition on the car is quite large, first of all, to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, the more and more desperate the more powerless. The second is to increase fuel consumption and increase your financial burden.

The third is the difficulty of cold start, that is, the difficulty of ignition, it is easy to get on the car without shooting, and finally the carbon deposit in the combustion chamber is strict, which will also cause cylinder detonation, and there is a sound of low-speed acceleration, which will cause damage to the piston and crankshaft, and cause the engine to hit the blue at high temperature, which will seriously affect the safety of the car. Then there is the excessive discharge, which not only fails the annual inspection and inspection, but also directly aggravates the harm of polluting the environment.

There is another reason: the throttle valve is faulty. Both of these problems can cause engine shake and unstable speed.

1. ThrottleWhen we step on the accelerator, the vehicle has some shaking, and most of the time it is a problem with the throttle. When carbon deposits or other pollutants are adsorbed on the throttle, it will cause the amount of air inhaled by the engine to be out of proportion to the amount of oil sprayed out of the fuel injector, resulting in insufficient fuel when the engine is working, resulting in body shake. In this case, you can go to the repair shop to clean the throttle.

Second, the spark plug spark plug as the ignition device in the engine, if there is a problem with the spark plug, then there is no ignition of the mixed gas in the cylinder, and the cylinder will not work, so that the power of the vehicle will decline, which is what we call the lack of cylinder. If you drive a lot, when the vehicle feels a strong shake and the vehicle has no power, and this shake exists from the start of the vehicle to the shutdown, then most of the spark plug is a problem. At this time, it is necessary to check whether the spark plug in a cylinder is broken.

The spark plug is a consumable, for the car owner, the spark plug should be checked during regular maintenance, and the spark plug should be replaced in time if the spark plug is almost depleted.

Third, the rubber ball cover itself is a consumable part, the main role in the body is also to play the role of shock absorption and dustproof, generally installed in the connection between the engine and other components, when the rubber sleeve is damaged, when stepping on the brakes, you will feel that the vehicle has shake, release the brake shake and disappear, in this case you will have to check the ball cover. Fourth, brake pads, as an important part of vehicle braking, play a vital role in the safety of vehicle driving. As long as you drive, you will use the brakes, so the longer the time, the more the brake pads are worn.

When the brake pads are worn more, when the brakes are applied, the braking effect will be reduced, the body will shake, and there will be some sizzling sound at the wheels when braking. Then it's time to check the brake pads and replace them in time. For the sake of our driving safety, we must check the vehicle in time and replace the damaged parts.

First of all, clean the throttle, if it is still shaking, clean the fuel injector, if it is still shaking, change a gasoline filter grid, if it is still shaking, check the ignition coil, if it is still shaking, check the CPU, if it is still shaking, it is gone.
