Logo 308 More than 50,000 kilometers Idling or driving the machine shakes and idling is unstable as

Signs of idle shaking, difficult starting, high idle speed, and excessive exhaust gas are all problems such as carbon deposits caused by poor combustion, and must be cleaned. Conventional vehicles must also be cleaned every six months or 10,000 kilometers to deposit carbon. It's a bit normal, just don't do it for a long time, because this will cause serious carbon deposition in the long term, resulting in a decrease in engine performance.

It is best to adapt to 10,000 kilometers of fuel additives once, so that it will be very clean and not black.

Hello, it is recommended to go to the repair shop with a special stethoscope to confirm that the engine part is making loud noise, to determine whether there is an impact and whether it can be repaired.

Hello, this situation is mainly caused by carbon deposits in the engine, it is recommended that you go to the repair shop to clean the carbon deposits on the throttle.

If you don't understand something, feel free to ask, and I will give you a satisfactory answer!

Summary. Dear, glad to answer for you! <>

Dear, when did you take care of your car?

Kiss, give you an extension <>

The air flow meter can measure the air flow into the engine and send a signal to the control unit, the air flow meter is damaged, which will cause the engine to not work normally, and there will be acceleration difficulties and idle jitter <>problems

My Peugeot 307, 2 years without maintenance appeared as a day, starting normally.

After half an hour, I was able to walk again, and then it stopped and reappeared.

Okay, dear, this will be caused by the air flow meter and fuel injector and carbon deposits, you need to replace the relevant parts and clean up the carbon deposits

Dear, this is caused by serious carbon deposition in the inlet tract and dirty throttle.

Dear, this is used by the engine hanging bottle method and adding fuel carbon deposition scavenger

Dear, you haven't maintained it for two years, and you still need to go to the 4S store to clean the carbon deposits

Good. Kiss, okay

Kiss, this is the cleaning of the throttle

Hello, the engine idle instability may be a slight lack of cylinder in the engine, check whether the spark plug gap is too large, whether the ignition coil is normal, whether the fuel injector is not atomized well, it is recommended to go to the repair shop to check.

Generally speaking, if the idle speed is unstable, it may be because the car's carbon deposits are relatively large, and it needs to be checked.

Hello! For the Peugeot 308 model, if there is an unstable idling, it is likely to be caused by the engine's throttle is too dirty.

Hello, the unstable idle speed of the Peugeot 308 should be caused by the carbon deposition of the throttle, try to clean the carbon deposition.

Hello, according to your description of the situation analysis, idle instability is generally caused by the engine throttle, fuel injector carbon deposition and spark plugs, it is recommended to clean the carbon deposition and check the spark plug at the same time, I am happy to answer for you!

Hello, according to your description, if your car is unstable at idle, you will have to check whether the throttle has carbon deposits that day, you can consider cleaning the lower throttle, cleaning the intake pipe, and it can generally return to normal.

Hello, this car is unstable at idle, the general situation is because the car engine has carbon deposits, it is recommended to clean it.

It may be that there is too much carbon deposit, it is recommended to clean the throttle valve, and after cleaning the carbon deposit, match it anew. It should be solved.

Hello, if the idle speed is unstable, it may be caused by carbon deposits in the engine, it is recommended to clean the throttle and fuel injector.

Hello, this unstable idle speed is usually due to the throttle or excessive carbon deposits in the engine.

If the idle speed of the sign 308 is unstable, it is recommended to check whether the throttle is dirty and caused by carbon deposits in the engine.

Hello, this needs to check whether there is any air leakage in the lower air intake system, and whether the vehicle throttle valve is caused by excessive carbon deposits

Logo 308: If the idle speed is unstable after the vehicle starts, the cold car should be started for a while, which is normal, and it is recommended to clean the throttle valve if it has been shaking.

This consideration is not caused by the serious carbon deposition of the throttle, clean up the carbon deposition of the throttle and replace the spark plug.

If the Peugeot 308 is unstable at idle, you need to check whether it is caused by excessive carbon deposition and clean the lower throttle.

Hello, if the idling speed of the logo 308 is unstable, it should be caused by a problem with the car's engine.

In this case, it is advisable to check the carbon deposition of the engine, which may be caused by excessive carbon deposition in the engine.

It is recommended to go to the four-S store to match it with a computer, the throttle is dirty, clean the throttle, and you can do it.

Hello, if this is the case, you can check whether there is some carbon deposits, and find professional personnel to repair it.

In your case, it should be that the engine throttle has too much carbon and needs to be cleaned, so it is recommended that you go to a local professional repair shop to check it.

Hello, your situation may be caused by too much carbon deposits in the car engine, it is recommended to clean it.

The shaking of the car after landing is an unstable idling, and the possible reasons are as follows:

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 deposition inside the engine is excessive, 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 carbon deposition is saturated, it is easy to get on the car, and the gasoline adsorbed on the carbon deposition 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. The lower the temperature, the greater the amount of oil required for the cold start, and the more the presence of carbon deposits will affect the cold start.

2. Ignition system problems.

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

3. The oil pressure is unstable.

If you have cleaned the engine carbon deposits, washed the throttle, changed the oil cushion and spark plug, etc., and still found that the body shakes 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 abnormal or the intake pressure sensor value is wrong and the work is poor, the body will shake.

It doesn't matter too much, it is recommended that you go and clean the throttle.

What should I do if there is a slight shaking in the idle speed of the imported Peugeot 308cc I know how to use it, I don't know how to wash it, all kinds of peculiar smells come out, inflammation is coming, and I have to take anti-inflammatory drugs, fortunately it is not serious enough to require surgery, otherwise it is inevitable to disembowel and break the belly. Take advantage of the young resistance and strong resistance, add a general fuel additive to the fuel tank for regular maintenance. In a good body, if you don't maintain it, you will soon not be able to do it.

A non-negligible cause is "carbon deposition", 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, more and 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 not easy to get on the car, and finally the serious carbon deposition in the combustion chamber 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 high temperature of the engine and 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.

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.

If carbon deposits occur in the valves and intake tracts of the engine, the ECU will make an error in judgment because the carbon deposits can absorb the appropriate amount of fuel. If the computer actually controls the injection of hypothetical 100 parts of oil and gas, but only 90 parts actually enter the cylinder (10 parts are absorbed by carbon deposits), then even if the remaining 90 parts of mixed oil and gas are fully combusted, this cannot achieve the required power, and the phenomenon of jitter is inevitable.

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 the carbon deposit inside the engine is too much and is demolished, the gasoline sprayed by the fuel injector during cold start will be absorbed by the carbon deposit, resulting in the mixture being too thin, 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 abnormal or the intake pressure sensor value is misaligned, it will also cause the problem of body shaking when idling.

Solution; The best way is to clean the oil circuit, clean regularly, from the new car to clean the engine research and development parameters have no specific experience, coupled with the continuous improvement of emission standards, can not adapt to the change of fuel, all manufacturers of the engine in the short term is unable to solve this jitter problem, plus the fuel quality is not very good or the new car factory initial fuel storage for too long, resulting in a rapid increase in the colloidal composition of the oil circuit, will continue to pollute the fresh fuel resulting in no good fuel can participate in the later combustion, 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 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.
