3008 Peugeot 13 models, 1 6t, unstable idle speed at cold start, black smoke, engine alarm! It is po

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.

In the case of a fault code, first go to the computer to clear the fault code and see where the code is reported.

Peugeot 3008 Idle Jitter Main Causes:

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 still found that the body is shaking, 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 poor, it 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 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 components 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 cars. We can only gradually alleviate most of the problems by maintaining clean oil circuits.

Summary. Hello, the temperature of the car is too high, then this situation is generally the cause of the failure of the coolant loss, or the electronic fan does not rotate, and the thermostat is damaged. It is recommended to do the following inspections and repairs:

First, first check if the engine coolant loss is causing the vehicle temperature to be too high. If the coolant loss is too serious, it will cause high temperature, and the coolant needs to be replenished in time. Second, check whether it is a phenomenon of high temperature caused by the non-rotation of the electronic fan?

In this case, it is important to check, is it an electronic fan fuse? Or the electronic fan does not rotate due to damage to the electronic fan control module. Third, the high temperature of the vehicle caused by the failure of the thermostat, which can generally be read out by the computer, and then if there is a problem, the thermostat assembly needs to be replaced in time.

What are the above points? The reason is that it is a relatively common fault that causes the vehicle temperature to be high, and this can take time to do the relevant inspection and maintenance.

Some cars shake and cold in relation to hot cars for about half a minute, don't worry about being on the road.

The car is hot, and then the car is still shaking, 4S says p gear throttle, 3000-4000 rpm, more than ten seconds. The fault light should be flashed when it is always on.

One reason is that it may increase the oil of the car, and there are impurities that can cause the car to shake and light the fault lamp. In this case, the driving lights themselves are a few days off.

If you are not sure what the situation is, go to a 4S store.

Then the car still shakes some car shake and the relationship between cold, 3000-4000 rpm. Hot car, hot car for about half a minute, more than ten seconds, light up the fault lamp, there are impurities can cause the car to shake. The fault light should be flashed when it is always on.

There is a reason for the possible increase in the car's oil. In this case, you have a few days off to drive the lights, don't worry about being on the road, go to consult the 4S shop, and the 4S says that the P block throttle. If you're not sure what's going on.
