Junwei's advice on engine noise and jitter

The reasons for Buick Junwei's engine shaking are as follows: the engine carbon accumulation is serious, and the most common reason for car shaking is the throttle valve too It is dirty or the fuel injector has too much carbon. When the engine accumulates too much carbon, the gasoline sprayed by the cold-start injector will be absorbed by the carbon accumulation.

Check whether it is a problem with the viscosity of the oil and replace the fluid oil.

When Junwei ignites, the engine shake may be due to incomplete combustion in the cylinder, resulting in insufficient power of the vehicle, and the vehicle shake may also be related to carbon accumulation. Focus on checking the volume carbon of the throttle valve. If the throttle valve has too much carbon, the vehicle will not be easy to start or idle at unstable speed.

Try to check the coolant. The oil pressure is too high or too low. Check the oil pressure gauge. It is also possible that there is a problem with the ignition time setting, which will also cause such symptoms. As for others, it may be an internal problem with the engine, such as EGR valve blockage. There is a hissing sound in the engine. There may be a problem. The engine is overheated. Check the cooling system.

It may be caused by the belt being too loose or too tight. It is difficult for ordinary car owners to distinguish which are faulty and which are reasonable. When I went to the repair shop to test the abnormal sound of the vehicles, only nearly 20% of the vehicles really had problems.

What is the reason for the idling jitter of Junwei engine

1. Buick Junwei idling jitterThere are the following reasons: fuel quality problems: According to statistics, the idling jitter problems encountered by most car owners are caused by fuel quality problems.

2. Common causes of car idling jitter may be: spark plug or ignition coil failure; valve timing is incorrect; cylinder compression is uneven; valve sealing, air leakage; poor fuel pressure; fuel injector blockage/leakage; leakage between cooling system and cylinder; air flow sensor failure, etc. Wait.

3. The main cause of idling jitter; the most common reason for vehicle jitter is that the throttle valve is too dirty or the fuel injector nozzle accumulates too much carbon.

4. Hello! The reasons for the vibration of the Buick Regal engine are as follows. The most common reason for the serious carbonization of the engine is the car's jitter is that the throttle valve is too dirty or the fuel injector nozzle has too much carbon. Give wayWhen there is too much carbon inside the engine, the gasoline sprayed by the cold start fuel injector will be absorbed by a large amount of carbon vapor. The engine lacks a cylinder engine.

Buick Junwei engine shakes, can't increase the speed, sometimes turns off

1 , the reason for the lack of cylinder. If the engine hasIf the cylinder does not work properly, the refueling door can only reach more than 2,000 runs. At this time, the engine shakes. You can check the ignition coil spark plug and fuel injector. Thank you for adopting it.

2. When Junwei ignites, the engine shake may be due to incomplete combustion in the cylinder, resulting in insufficient power of the vehicle, and the vibration of the vehicle may also be related to carbon accumulation. Focus on checking the volume carbon of the throttle valve. If the throttle valve has too much carbon, the vehicle will not be easy to start or idle at unstable speed.

3. There are many reasons. The situation I encountered before is that the front oxygen sensor is broken, and it will be fine after replacement. You'd better go to the 4S store for a check.

4. The reasons for the vibration of the Buick Regal engine are as follows: The most common reason for the serious carbonization of the engine and the car's jitter is that the throttle valve is too dirty or the fuel injector nozzle has too much carbon.

What's wrong with the idling jitter of the Buick Junwei (what is the reason for the idling jitter of the Buick Junyue)

The engine has serious carbonization, and the most common reason for car jitter is the throttle valve Dirty or too much carbon in the fuel nozzle.

Serious idling vibration is generally caused by engine cylinder shortage, aging or loose foot glue, carbon accumulation, fuel system failure, etc. Serious carbonisation of the engine: Cars always have the problem of carbonisation, including cylinder carbonization, throttle carbonisation, spark plug carbonation, intake carbonation, etc.

The reasons for the vibration of the Buick Regal engine are as follows: the engine has serious carbonization, and the most common reason for car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon.When the engine accumulates too much carbon, the gasoline sprayed by the cold-start injector will be absorbed by the carbon accumulation.

The engine has serious carbon accumulation. The most common cause of idling jitter is excessive carbonisation of the throttle valve or fuel nozzle.

The main reason for idling jitter; the most common reason for vehicle jitter is that the throttle valve is too dirty or the fuel injector has too much carbon.

When Junwei ignites, the engine shake may be due to incomplete combustion in the cylinder, resulting in insufficient power of the vehicle, and the vehicle shake may also be related to carbon accumulation. Focus on checking the volume carbon of the throttle valve. If the throttle valve has too much carbon, the vehicle will not be easy to start or idle at unstable speed.

Junwei's engine shakes at 90 water temperature

Cleaning up engine carbon is an important reason for excessive engine carbon accumulation, mainly due to the use of inappropriate oil.It is recommended to add a certain amount of detergent when refueling, and after you finish cleaning, you'd better drive at a high speed, which is conducive to increasing the exhaust volume and allowing the strong airflow to bring out larger carbon particles.

The most common reason for car jitter may be the dirty throttle valve and too much carbon accumulation in the fuel injector.

The engine has serious carbonization. The most common reason for car shaking is that the throttle valve is too dirty or the fuel injector has too much carbonization.

The reasons for the vibration of the Buick Regal engine are as follows: the engine has serious carbonization, and the most common reason for car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon. When the engine accumulates too much carbon, the gasoline sprayed by the cold-start injector will be absorbed by the carbon accumulation.

What to do if the engine of Buick Regal shakes.

Solution: Clean the oil road and check whether the idling motor has carbon accumulation, which should be cleaned. Jitter caused by the system: The ignition jitter of the system is usually caused by ignition coils and spark plugs. It is mainly to check whether the ignition coil is missing signal, poor contact, and module failure.

Focus on checking the carbon volume of the throttle valve. If the throttle valve has too much carbon, the vehicle will not be easy to start or idle at unstable speed. Every time the vehicle starts the engine, it should open the ignition key for about 3 seconds before starting the engine, so that the PP electronic trottle can adapt to learning, and the fuel system can also establish the oil pressure before starting the engine.

It seems that this situation is generally caused by poor combustion of the engine. It is recommended that you replace the spark plugs and clean the fuel injector with the repair shop.
