Has the idle jitter problem of Citroen C6 been solved?

There are four main causes of body shake 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.

In addition, 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 smooth cold start. The solution is to clean the oil circuit and check whether the idle motor has carbon deposits that should be cleaned.

2.Problems with the ignition system.

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 is not in good condition and the spark plug is not in good condition. The solution is to check the spark plug for excessive carbon accumulation and replace the spark plug.

3.The oil pressure is unstable.

If you have cleaned the engine charcoal, washed the throttle, changed the oil cushion and spark plug, etc., and still found that the body shakes when idling, it is recommended that you 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 is wrong and the work is not good, the body shakes will be caused by abnormal oil pump pressure pressure or wrong intake pressure sensor and poor work. The solution is to check the oil pressure and replace the parts if necessary.

4.Aging of engine components.

Car jitter is also associated with aging of the engine feet. The engine foot is actually the suspension system of the engine, and the engine foot is responsible for absorbing the subtle shake of the engine when it is running, and if there is a problem with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing shaking when idling.

The specific causes and solutions of unstable idling after the car starts:

1.Intake manifold leakage: When the air, gasoline vapor and combustion exhaust gases that should not enter the intake manifold, the mixture is too thick or too thin, resulting in unstable idling of the car.

Solution: Check the manifold and replace it in time if there is any air leakage.

2.Excessive carbon deposition on the throttle: excessive carbon deposition on the throttle and surrounding air intakes, and changes in the cross-sectional area of the airway, which makes the control unit (check the transaction price|Matching|preferential policies) cannot accurately control the idle air intake, which also causes the mixture to be too thick or too thin, resulting in unstable car idling.

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.

The steering wheel shakes when the car is idling, which is very common, and some car owners can feel a strong steering wheel shake when driving the car at high speeds, when the speed reaches 80-100km h or more. In this case, most of the problems occur in the tires of the car, because the uneven distribution of the mass of the whole part of the tire will cause the wheels to rotate at high speed, and there will be a dynamic imbalance state, which will cause the steering wheel of the car to shake seriously while driving. In this case, it is necessary to align and dynamically balance the tires of the car, and in serious cases, the tires must be replaced.

In addition to the tires of the car, there may also be shock absorber failure, frame deformation, excessive meshing clearance of the main and driven gears of the final reducer, etc. If the steering wheel shakes when braking while driving, then it is very likely that the brake force is too strong and too frequent, which may cause the brake disc and brake pads to overheat and deform when cold, causing the steering wheel to shake.

Generally, the symptoms can be solved after replacing the brake discs and brake pads. If the speed of the vehicle is not fast, but the steering wheel shakes, it is possible that the steering belt of the mechanical steering system will slip when the belt is too loose, which will also cause the steering wheel to shake, and there will be shaking and abnormal noise when the steering transmission system is loose and the gap is too large, but this situation is rare.

Citroen C6 idle shake problem solved, engine idle shake fault diagnosis generally has several situations, the engine carbon deposition is serious and the most common cause of car shake is the engine internal division of the general cleaning agent, can remove carbon deposition without dismantling the engine oil to clean carbon sludge, it is very convenient to use, suspension differentiation does not clog together, and miscible with oil will not lead to delamination, better and safer cleaning your engine.

Hello, my friend's car does not have this problem, you can see if it is caused by the throttle.

The shortcomings and failures of Citroen C6 are: unreasonable trunk design, unreasonable storage space, high fuel consumption, abnormal vehicle noise and unfriendly to novices.

1. The trunk design is unreasonable.

The design of the trunk support bar is too poor, and the connecting rod inside will also squeeze the trunk during opening and closing, so it can be said that the Citroen C6 does not have a trunk at all!

2. The storage space is unreasonable.

There is no glasses case, and there is also a handle on the co-pilot's position, this design is very chicken, and the front door design is also very speechless, the door frame is too abrupt, and you will hit yourself in the face if you don't pay attention when you open the door.

3. High fuel consumption.

The official data is that the actual high-speed fuel consumption is around 11.

4. Abnormal noise of vehicles.

The engine has a strong sense of idleness, and there will be shaking at the start, which makes the glass of the sunroof part shake together with the sunshade and make a very loud noise.

5. It is not friendly to novices.

In the normal sitting position, the steering wheel completely blocks the rear wipers, lights, and cruise control lever, which is unfriendly to people who just get in the car and don't know where the control keys are, and may be a safety hazard.

As an auto mechanic, I recommend you go to a car repair service station and check it out! The start-up jitter of the car can be big or small! To put it mildly, there will be a slight jitter when the car starts!

To say bigger, the car starts to shake and there may be a fault in the ground, it is recommended that you repair it as soon as possible, after all, the car is driven by yourself, and you must be responsible for your own safety!

Summary. Dear, I'm glad to answer your <>

Citroen C6 starts, and the reasons for engine starting failure are as follows: 1. The oil pressure of the fuel system is unstable. 2. The engine throttle is too dirty, which exceeds the limit of engine ECU adjustment.

3. The engine has serious carbon deposits. Among them, the third situation is the most common, it is recommended to clean the engine carbon deposits. <>

<> Citroen C6 started shaking, and there was an engine starting failure.

Dear, I'm glad to answer your <>

Citroen C6 starts, and the reasons for engine starting failure are as follows: 1. The oil pressure of the fuel system is unstable. 2. The throttle valve of the engine is too dirty, which exceeds the limit of the ECU adjustment of the engine.

3. The engine has serious carbon deposits. Among them, the third situation is the most common, it is recommended to clean the engine carbon deposits. <>

<> hello dear, extended content: The first case needs to check the oil pump, control valve, and check the oil balance. In the second case, you need to clear and tremble the brother to wash the hole and stimulate the throttle. [Great Strike Saffron] <>

1. Excessive carbon deposition in the motor cylinder is serious, which will cause nozzle congestion and valve congestion, which directly causes the car to tremble when idling. Second, the failure of the oil supply system, the unstable pressure of the lubricating oil is easy to cause the concentration of the mixed gas to be unstable, which will cause shivering and unstable idling. Third, the aging of the motor claw pad is not a common cause of trembling.

The car is shivering for the sake of it:

1. If the carbon deposit in the motor cylinder is serious, it will cause the nozzle to be congested and the valve to be congested, which will directly cause the car to shiver when idling. If the car's speed is not as good as before, and the trembling is very long, then you can consider cleaning the inside of the motor cylinder.

Second, the failure of the oil supply system, the unstable pressure of the lubricating oil is easy to cause the concentration of the mixed gas to be unstable, which will not only cause shivering, but also cause the phenomenon of unstable idling. You can first consider replacing the gasoline grid, and finally the filter element may be congested after a long time, and then check the lubricating oil pressure that does not pass through the gasoline grid, if it is abnormal, it may be a problem with the oil pump.

3. The aging of the motor claw pad is also a non-common trembling reason, if your car motor trembling is getting more and more serious, but the PS has not weakened, you can consider whether the claw pad is the problem.

Fourth, the lack of cylinder and lack of fire This is the most common reason for the motor to tremble, or even one, the problem lies in the motor lighter coil or nozzle, if the ignition coil emerges a problem or the nozzle can not jump for some reason, then the car will appear trembling state.

Pacific Automobile Network] Citroen C6 ignition moment car jitter reasons: 1. The fuel system oil pressure is unstable; 2. The engine throttle is too dirty, which exceeds the limit of engine ECU adjustment. 3. The engine has serious carbon deposits.

Causes of abnormal noise in the chassis of Citroen C6 cars:

1. Interference between parts;

2. Loose bolts or nuts;

3. Transmission shaft universal joint failure;

4. Abnormal noise caused by damage to each ball joint, suspension and connecting bracket;

5. Abnormal noise of braking system.

Citroen C6 chassis material is made of resin, and the chassis using this material is judged because the chassis of this material has high strength, high rigidity, good stability, and at the same time can reduce weight, and can ensure strong longitudinal support and shock absorption effect.

Citroen C6 chassis:

1. Citroen C6 adopts MacPherson independent suspension, which is simple in structure, relatively low in cost, and occupies less space.

2. The lower control arm adopts the casting process, compared with the stamping process, although the mechanical properties of the casting parts are general, it has the advantages of wear resistance, corrosion resistance and vibration absorption, which can not be done by the stamping process;

3. Citroen C6 lower control arm adopts a ball head that can be replaced separately, in the later maintenance of the car, it can save more costs, in general, an independent ball head only needs dozens of pieces, and a whole lower control arm may cost hundreds of yuan or thousands of yuan, so this is the benefit of independent ball head;

4. In terms of bushing, Citroen C6 adopts the hydraulic bushing connection of the ear beam, when the car passes through the speed bump or the uneven road surface of the pit clan, the hydraulic bushing can absorb the effect of vibration filtration and improve the comfort of the vehicle.

Hello, it may be caused by the throttle being too dirty, clean the throttle and replace the spark race.

Check the spark plugs, ignition coils, fuel injectors, throttle valves.

High-end luxury cars and new cars are facing jitter, high-end cars have a large compression ratio, high fuel requirements, domestic fuel is the characteristic, engine manufacturers are based on the mainstream fuel appearance, there is no research on ethanol fuel.

In fact, it is not a problem with the engine, as long as you use a detergent to clean it once, you don't have to worry about this situation, add 1 to 2 Siyoupu fuel additives according to the size of the fuel tank, and run one or two tanks of fuel, and the jitter before the D gear is good.

Hello, the idle body shakes should be a broken chicken paw frame or the engine is missing cylinders.

Is it normal for Citroen Sega to idle shake, there are generally several situations of engine idle shake, gear start shaking, cold start, three-way catalytic temperature is not enough, and the most common reason for car shake caused by serious engine carbon deposition is that the throttle is too dirty or the fuel injector has too much carbon deposit, 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 jitter after cold start. Solution: Siyoupu cleans the oil circuit and checks whether the idle motor has carbon deposits and should be cleaned.
