Peugeot 3071 6AT25000 km after starting is engine shake, what is the reason 10

The first thing to see if the engine is lit up.

If it's bright, then 80% of it is a carbon deposit.

Peugeot kilometers can easily generate carbon deposits if they are not driven well.

In addition, the general solution to jitter is to replace the spark plug and gasoline grid and clean the throttle.

These to your 30,000 kilometers to go to the 4S store to do B insurance also have these projects.

Therefore, it is recommended that you go for B insurance in advance.

The cost of B insurance can be called** to 4S consultation.

It is generally 1000 yuan.

Actually, no, the jitter has something to do with the braking system, I don't know if yours is automatic

I'm self-draining, so when I apply the brakes, it will fight.

The cold machine is also a bit

It's not a big problem, don't worry.

Walk down more often than you want to start.

The fuel injector is dirty, right? When the car is hot, it doesn't shake.

Normal!! My car has been shaking since the day I bought it, but I never noticed it before!! ~

My car, cleaned the fuel injector and engine, the shaking is still there, it is recommended to go to the 4s point to check, but basically there is no result, at most is to change the spark plug for you, and clean it again. Personally, I think it's because the damping system is aging.

I don't know if the magnitude of the shake is large, and the 307 itself is a high-revving engine, which will be larger than that of Japanese cars.

If the shaking is very large, it is recommended that you go to the 4S store to check if the fuel injector is dirty, and the yellow warning triangle under the dashboard will be on.

1. There are many reasons for the deliberate light to be on.

1.The fault light is the most intuitive signal for the driving computer to remind the driver whether the vehicle is faulty, and the fault light is lit, which means that there is an abnormality in a certain system of the car. It is sent to the driving computer by the sensor detection data, and analyzed and judged by the driving computer, and displayed through the dashboard.

2.The indicator lights distributed on the dashboard do not all refer to fault lights, they can be roughly divided into three categories: warning lights, warning lights, and fault lights.

Usually these indicators are also divided into green, yellow, and red colors according to the different risk factors (suitable for most models). When the red light is on, the driver is better to stop immediately.

Second, the cause of engine shaking can be measured by relevant instruments, and manual diagnosis can be carried out.

Fault diagnosis instrument KT300 read the car system fault code, if the following three fault codes appear, the fault codes are: P0480 (cooling fan high-speed failure), P1336 (multi-cylinder lack of fire) and P1340 (4-cylinder lack of fire). Clear the engine control unit fault code, test run, and the engine is normal.

Our initial diagnosis was that the fault code was caused by the driver's short starting time, but the driver firmly denied our statement, and reflected that the fuel consumption of the car was significantly higher than that of the new car.

The ignition waveform of the ignition system of the car was detected, and after the ignition waveform problem was eliminated, the engine data stream was read, and no problem was found. The engine oil pressure was detected, and it was normal.

Removal of carbon deposits from the engine cylinder. Remove the cylinder head to remove carbon deposits from the engine cylinder.

One is to add qualified oil to the car and add some additives to the fuel tank in a timely manner; The second is to make the car drive a certain mileage on the highway from time to time.

Hello: Generally, the idle speed of hot cars is less than 800 rpm. Idling will shake.

The idle jitter of the vehicle is due to the throttle. The inlet air pressure is the sensor. or air flow meter. The idle motor is dirty. Just wash it and wash it.

Other than that. Whether the air intake mispath is leaking with the spike and whether the vacuum booster pump is leaking. Whether there is any air leakage in the inlet pressure sensor and fuel injector.

It is also something to watch. In this case, you can measure the vacuum degree of the engine. It can also lead to unstable idling.

1. Dirty air filter: The air filter is designed to protect the engine and reduce wear, and is generally replaced at about 10,000 kilometers.

2. High-voltage wire fibrillation breaking: high-voltage wire breaking refers to the opening of the high-voltage wire core, which can affect the ignition and cause engine shaking.

3. Spark plug life: The spark plug has a lifespan, and the ignition efficiency is significantly reduced after more than 3-40,000 kilometers, and can affect the ignition, which is the most common failure, and the spark plug can be replaced all.

Most of the cold start jitter is caused by poor fuel combustion, the fuel tank has more gum moisture, 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.

There are several causes of engine shake;

1. The engine has serious carbon deposits, and the most common car with serious shake is that the fuel injector throttle valve is too dirty or too much carbon;

2. Ignition system problems, check the working conditions of spark plugs, high-voltage wires and ignition coils;

3. If the oil pressure is unstable, if the pressure of the pump is abnormal or the error and poor work of the inlet pressure sensor will cause the body to shake;

4. Aging of engine parts; Excessive carbon deposits in engine emissions absorb carbon from the gasoline of the cold-start injector, which leads to a dilute cold-start mixture and difficulty starting.

Specific solutions to 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 is not properly supplied or the intake pressure sensor is incorrect, it will also cause the body to shake at idle.

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.

Peugeot 307 has idle jitter, due to serious engine carbon deposits, ignition system problems, unstable oil pressure or intake pressure sensor values, aging engine parts, etc., it is recommended that the owner go to the maintenance point for maintenance.

Dirty throttle valves or excessive carbon build-up in fuel injectors are the most common causes of car chatter. The combustible mixture of the engine is sometimes dilute and sometimes thick, causing the idle shake after cold start. We should clean the oil circuit and check the idle motor for carbon deposits.

There is a problem with the ignition system, and we need to check the working condition of the spark plugs, high-voltage wires, and ignition coils. Check the spark plug for excessive carbon build-up and replace the spark plug. Abnormal oil pump supply pressure or incorrect intake pressure sensor and poor operation can cause body shake.

If the owner has cleaned the engine deposits, washed the throttle, changed the oil pad and spark plug, etc., the body shake cannot be solved when idling. It is necessary to check whether the fuel supply pressure and the inlet pressure sensor are normal.

Shaking can also occur when engine components are aging, such as engine feet. The engine foot is the shock absorption system of the engine, the engine foot is responsible for absorbing the subtle shaking of the engine when it is running, if there is a problem with the engine foot, these vibrations will be transmitted to the steering wheel and the cab, causing Qinghuai Xiang to shake when idling.

408 The main cause of idle jitter;

1. The most common reason for 408 jitter is that the throttle valve 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 started, 3. The gasoline adsorbed on the carbon deposition after the car will be sucked into the cylinder by the vacuum suction of the starting wide family machine for combustion, and the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, resulting in the idle shaking after the 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 circuit, which will continue to pollute the fresh fuel and cause no good fuel to participate in combustion in the later stage. We can only gradually alleviate most of the problems by maintaining clean oil circuits.

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 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, so that the hole can solve the problem caused by carbon deposition by using fuel additives such as PNF stock solution. 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 maintain and clean the oil road, so that we can gradually alleviate most of the problems.

What is the reason why the Peugeot 307 shakes badly when it starts cold?

Hello pro, the car starts cold, starts off, or shakes is the cause of carbon deposits. Carbon deposits usually appear on the inner wall of the throttle valve, the head of the intake valve, the inner wall of the intake tract, the top of the piston and the wall of the combustion chamber. After the water temperature reaches the normal working temperature of the engine, the computer repeatedly adjusts the position of the throttle valve plate, causing the idle speed to fluctuate.
