What s the deal with the Peugeot 508 jitter?

Most of the cold start jitter is caused by poor fuel combustion, the fuel tank has more gum moisture, too much carbon deposition inside the engine, and the cold start is not brought to the combustion chamber and then mixed in the fuel tank is driven into the combustion chamber, and the jitter caused by poor combustion. The gasoline emitted by the cold start injector will be absorbed by carbon deposits, resulting in a dilute mixture for the cold start, which makes the start jitter.

The most fundamental reason for the shaking phenomenon of cold start or waiting in neutral is poor combustion in the cylinder. If the combustion is not good, the power provided by the car will not be enough, and the car will shake.

Causes of idle jitter:

1. The engine has serious carbon deposits. The most common cause of idle judder is excessive carbon build-up on the throttle or injector. When there is too much carbon deposit inside the engine, the gasoline sprayed by the fuel injector during cold start will be absorbed by the carbon deposit, resulting in a mixture that is too thin and making it difficult to start.

After landing, the gasoline adsorbed on the carbon deposits will be sucked into the cylinder by the engine and burned, which will thicken the mixture. The mixture is sometimes dilute and sometimes thick, which will cause idle jitter after cold start. The lower the temperature, the greater the amount of oil required for cold starts, and the more the presence of carbon deposits affects cold starts.

The solution is to clean the carbon deposits at the throttle and injector.

2. Poor ignition system and poor ignition of spark plugs will also lead to engine idling and shaking. If there is a problem, check if the ignition system is faulty and if there is too much carbon deposited in the spark plug.

3. The oil pressure is unstable. If you have cleaned the engine carbon deposits, cleaned the throttle valve or replaced the spark plug, and there is still the problem of body shaking when idling, it is recommended to go to the 4S shop to check whether the fuel supply pressure and intake pressure sensor are normal. If the oil pump supply pressure is not normal or the intake pressure sensor is incorrect, it can also cause the body to shake when idling.

Solution; The best way is to clean the oil circuit, clean it regularly, there is no specific experience in the research and development parameters of the clean engine from the new car, coupled with the continuous improvement of emission standards, can not adapt to the change of fuel, all manufacturers of the engine are unable to solve this jitter problem in the short term, plus the fuel quality is not very good or the initial fuel of the new car factory 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. The occurrence of excessive carbon deposits is especially common for China VI vehicles. We can only gradually alleviate most of the problems by maintaining clean oil circuits. The use of PNF dope fuel additives can solve the problems caused by carbon deposition.

The main reason for the shaking of the car at the start is that there is more carbon deposition on the throttle, or it is caused by the poor coordination of oil separation during starting. 1. The carbon deposition at the throttle makes it impossible for air to enter according to the size of the throttle opening, resulting in the air-fuel ratio imbalance, so there is a phenomenon of shaking. It should be noted that when cleaning the throttle, it is not possible to wash the throttle valve alone, the throttle idle valve must be disassembled and cleaned, and the idle valve bearing must be lubricated with oil.

We hope you find this service helpful. If it helps you, we look forward to your likes and attention.

First of all, your question is the cause of the Jeugeot 508 jitter, there are several reasons. The first common aspect is whether the ignition defect caused by the addition of ordinary inferior gasoline is a malfunction. The second common problem is that the ignition system failure mainly includes leakage of the ignition coil, too large gap of the spark plug, and poor ignition.

The third aspect is mainly the group side, which mainly includes the carbon deposition of the throttle, the carbon deposition of the fuel injector, and the poor combustion caused by the deposition of carbon in the rubber cylinder. Fourth, I would like to consider the sensor, which is generally the oxygen sensor.

Hello, I would like to ask the next 14 signs, 508 displacement, acceleration is normal, there is no problem, when the throttle is returned, the vibration in front of the engine is relatively loud, what is going on, the parking gear is buried in the gas pedal, and it is okay that the oil return is a round liquid difference, and the engine should vibrate orange peel.

In this case, the main thing is the engine resonance, which is generally due to the loosening of the engine bracket screws or the aging and loose deformation of the bracket.

It's not that the foot glue is broken.

It's not that the foot glue is broken.

Is there any problem with the engine mounts and engine screws inspection?

In this case, check whether there is any air leakage in the system recently, and secondly, check the fuel injector and ignition system.

There is a shake when the throttle is closed.

If Xiang Tsai also shakes in situ, it will be ignited, and this kind of cautionary response to Wang mainly considers the ignition fuel injection system and air intake system of the engine itself. It's important to consider the air intake system.

Okay, I'll just have to take a look.

Well, okay, I hope mine can help you.

If I can help you, please give me a thumbs up Thank you!

I can't solve the problem of 508, it's like this, it's even more powerful to turn on the air conditioner, and I can't try it when I open it.

Does a new car shake when it idles? Then hurry up and find a 4s free solution.

The main causes of Peugeot 508 idle jitter:

1.Serious engine carbon deposition: The total megalimb of the car has the problem of carbon deposition, which includes cylinder carbon deposition, throttle carbon deposition, spark plug carbon deposition, intake carbon deposition, 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 still found 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 oil supply pressure is abnormal, or the value of the intake pressure sensor is wrong, the work is not bright, and the guess is good, which will lead to body shaking.

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 fumes coming out of the car are obviously intermittent, and the exhaust pipe shakes violently, and the engine shake can be clearly felt, 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 problem of carbon deposition caused by the above-mentioned 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 main cause of idle jitter;

1. The most common cause of vehicle shaking is that the throttle is too dirty or the fuel injector has too much carbon.

2. When the carbon deposition inside the engine is too much, the gasoline sprayed by the cold start fuel injector will be absorbed by the carbon deposition 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 deposition is saturated, it is easy to get on the car, 3. After the car, the gasoline adsorbed on the carbon deposition 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, resulting in idle shaking after cold start. The lower the temperature, the greater the amount of oil required for the cold start, and the more carbon deposits will affect the smooth cold start.

Severe idle vibration is generally caused by engine cylinder failure, aging or loose foot rubber, carbon deposits, fuel system failure, etc.

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 dispersion, which will continue to pollute the fresh fuel and cause no good fuel to participate in the combustion in the later stage, and the carbon deposition exceeds the standard. We can only gradually alleviate most of the problems by maintaining clean oil circuits.

Analysis of the original circle of automobile jitter:

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 car must be balanced once when replacing 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 too high idle speed, and the carbon deposit generated by the engine in the 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.

What is the Peugeot 508 engine shaking What is the Peugeot 508 engine shaking The reasons for the shaking of the inventory machine may be: 1. It may be that the air flow sensor, fuel consumption sensor and other signals in the engine are relatively chaotic, resulting in deviation in the acceptance of the computer; 2. It may be because the engine oil does not keep up in time when the engine is running, so that the engine does not get better mechanical operation conditions, resulting in engine shaking; 3. It may also be that there is a problem with the computer board of the vehicle itself, and the driving computer receives an error signal from the starting wild machine, or the signal given is chaotic, resulting in the problem of engine shaking. @2019

I don't know if it's normal for the vehicle to have a sudden brake shake, I have never tested it like this, I don't know if it's normal for the vehicle to have a sudden brake shake, I have never tested it like this Brake shake, there may be more original Nachain involved. The most common reason is that there is a problem with the brake pads and brake discs. It may be that the brake disc is severely worn on one side.

The unilateral wear of the brake disc is serious, which is generally caused by the poor return of the brake cylinder. Solution: Check to see if there is a problem with the brake pump first.

If there is a problem with the brake cylinder, repair or replace it. If the brake cylinder is fine, replace the brake disc directly. It is also possible that the brake pads or brake discs are deformed due to jitter.

Brake disc may be the brake disc wear groove is particularly deep It should be a problem with the brake disc, you can go back to the 4S shop to check it You brake ABS intervention work like this! If the speed of the speedometer is 0, and the top foot feeling of the fast frequency of the foot brake pedal is normal, if the speed is not 0, it is normal that the normal emergency braking car has not stopped, then it is 100% abnormal, including the sudden braking when the speed is very fast, let go of the steering wheel when braking, if the steering wheel is active when the steering wheel starts to brake when the brake starts, if it is a more dog 13 A little bit of the car or even the steering wheel begins to twist on its own, it is abnormal! If there is any change in the steering wheel during this period, it means that the car is not very good!

You can go back to the 4S shop to check the brake disc, it may be deformed, do the dynamic balance of the brake disc The anti-lock braking system is started, and it is normal to grind the light gear balance disc to solve it Normal, ABS intervenes, you can test it yourself on the road where no one is there Do you send the wrong section It should be ABS intervened When braking at high speed, when the brake disc is restrained by the brake caliper, the uneven brake disc will vibrate, and be transmitted to the body and steering wheel through the steering lever and suspension, resulting in body vibration and unstable direction. The jitter you are talking about should be the ABS starts when braking, resulting in anti-lock braking of the vehicle. @2019
