My Hyundai Yuedong idle engine shakes the car powerless, what s going on, hurry, hurry! 10

See if the throttle is dirty, that is, the intake valve body, if it is dirty, use carburetor cleaner to clean the flap near it, and it's OK.

Lack of cylinders. Unplug the high-voltage cable. Check which tank doesn't work. If you can't change the activator plug, change the cylinder line. Try the ignition coil!

It is estimated that you are in a hurry to hit the road without a car! When it first started, many oil circuits did not go through. Rushing to the road will only suffocate the engine. So after a few minutes of hot car before leaving!

My Hyundai Yuedong idle engine shakes the car powerless, what's going on, hurry, hurry! Long-term cleaning of the oil circuit, the top of the valve of direct injection can be cleaned and clean. The so-called carbon deposit is more in the cleaning that is maintenance, the maintenance cost is high, the process is troublesome, the car is seven points of maintenance and three points of repair, to the maintenance of the oil road is the same reason, why many people are not in a hurry to clean, just like the tooth does not hurt is not in a hurry, the pain is in a hurry.

My Hyundai Yuedong idle engine shake car powerless what's going on 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 idle shake fuel additive cleaning agent, which can remove carbon deposition without disassembling the engine oil to clean the carbon sludge, it is very convenient to use, the suspension differentiation is not blocked, and it is miscible with the engine oil and will not lead to delamination, better and safer cleaning of your engine.

You see if it's a clutch plate.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, I hope this service can help you. Hyundai Yuedong refueling is weak and shaking, and the following reasons are mainly considered for this situation.

The first common aspect is whether the ignition defect caused by the addition of ordinary inferior gasoline to the oil quality problem is a failure. 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 problem of poor combustion caused by throttle deposition, fuel injector deposition and in-cylinder carbon deposition.

Fourth, I would like to consider the sensor, which is generally the oxygen sensor.

Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, I hope Qiaokai this service can help you. Hyundai Yuedong refueling is weak and shaking, and the following reasons are mainly considered for this situation. The first common aspect is whether the ignition failure caused by the addition of ordinary inferior gasoline is a problem with the quality of the oil.

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

There are many possibilities for the car to be weak when idling and jittering, and the actual causes may be as follows:

Unreasonable fuel labeling causes detonation.

Long-term low-speed driving causes carbon deposits on valves and throttles.

Inferior gasoline causes engine shake, and insufficient antifreeze causes gasket ablation.

The engine is missing cylinders, the cylinder line or the ignition coil is faulty.

Poor assembly leads to poor cylinder sealing.

A faulty timing system causes problems with the gas distribution.

My Hyundai Yuedong idle engine shakes the car powerless, the car accelerates weakly, this is not a big problem, first the computer detects 1 Check the sensors around the engine, the computer can detect the fault code 2, detect the transmission fault code, the computer can detect;

3. According to experience, it is to clean the oil circuit, the fuel vehicle will accelerate powerlessly, and the fuel vehicle will accumulate carbon. You can use the amount of heat, Si Youpu idle jitter fuel additives fuel additives, Wu Qilai, Chengxing Light fuel additives to clean, these are my personal tests are effective, can clean water and carbon deposits, the effect is good.

Main causes of idle jitter:

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 gas flowing out of the car is obviously intermittent, and the exhaust pipe shakes violently, and the engine shakes clearly, 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 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.

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 carbon deposition is serious. The most common cause of idle judder is excessive carbon build-up on the throttle or injector. When there is too much carbon deposition inside the engine, the gasoline sprayed by the fuel injector during cold start will be absorbed by a large amount of carbon deposition, and the mixture is too thin due to forest rent, 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: Ode to friends;

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.

Carbon deposits will cause insufficient combustion of gasoline, which will cause the engine to shake, and the carbon deposits can be recovered by cleaning.

The impact of engine carbon deposits on the car is quite large, reducing the engine power, that is, making the power output uneven and gradually decaying, in other words, more and more powerless.

The other is to increase fuel consumption, increase the economic burden, cold start difficulty, that is, the difficulty of ignition, not easy to get on the car, and finally the combustion chamber carbon deposition is serious will also cause cylinder detonation, low speed acceleration has a sound, causing damage to the piston and crankshaft, thereby seriously affecting 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.

Hyundai Yuedong ( Check price |The reason for the idle speed shake is that carbon deposition will cause insufficient gasoline combustion, which will cause the engine to shake. It may increase fuel consumption and increase the economic burden. It is difficult to start cold, that is, it is difficult to ignite, it is not easy to get on the car, and finally the serious carbon deposition in the combustion chamber will also cause cylinder detonation.

Hyundai Yuedong engine idle jitter:

1.Severe carbon deposits in the engine: The most common cause of car shake is a dirty throttle valve or excessive carbon buildup 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. The solution is to clean the oil circuit and check whether the idle motor has carbon deposits and should be cleaned.

2.Ignition system problems: Check the working conditions of the spark plugs, high-voltage wires and ignition coils, poor ignition system work and poor spark plug flashover conditions will also lead to this kind of failure. The solution is to check the spark plug for excessive carbon accumulation and replace the spark plug.

3.Unstable oil pressure: If you have cleaned the engine carbon deposit, washed the throttle, changed the oil pad 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 value of the inlet air pressure sensor is wrong and the work is not good, the body will shake.
