What should I do if the Jinbei Hiace 4Y engine idles and shakes

There are four possible causes of jitter:

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.

2.Problems with the ignition system.

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

3.The oil pressure is unstable.

If you have cleaned the engine deposit, washed the throttle, changed the spark plug, etc., and still found that the body shakes when idling, it is recommended 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 not good, the body shakes will be caused by abnormal oil pump supply pressure or wrong intake pressure sensor value and poor work.

4.Aging of engine components.

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

Summary. Hello, happy to answer your questions.

Jinbei sea lions, unstable idling, shaking of the car, stalling during driving, how to solve it.

Hello, happy to answer your questions.

Hello. If this car first has this problem, you should use a computer to check it to see if there is a fault code. If there is no fault code, it is usually caused by the oil circuit.

For example, the oil supply is not good. There is also the idea that you use your computer to look at its associated data streams. For example, the air flow meter, then the inlet pressure, the oxygen sensor.

A cause that cannot be underestimated is "carbon deposit, 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 cold start.

Difficulty, that is, the difficulty of ignition, not easy to get on the car, and finally the serious carbon deposition in the combustion chamber will also cause cylinder knocking, low speed acceleration with sound, to the piston and crankshaft.

Causing damage, causing high engine temperatures and seriously affecting car safety. 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.

There was a malfunction. Both of these problems can cause engine shake and unstable speed. It is recommended that you check the carbon deposits of the cleaning engine.

What you need to note is that the throttle and idle motor can be removed directly for cleaning; The intake tract, intake valve and combustion chamber can be inspected with endoscopy first, and if the carbon deposit is not too much, it can be dismantled and cleaned; If more, it is recommended that you use a plug from a spark.

The method of hole spray cleaning liquid to wash the carbon deposit in the combustion chamber, a good decarbonizer is driven into the combustion chamber by special equipment in the form of foam from the spark plug hole, the carbon deposit in the combustion chamber is melted away, and then these liquid carbon deposits are sucked out from the spark plug hole, and the cleaning effect is known from the color of the sucked substance, and this method is currently the best in the case of non-disintegration. Also check the spark plugs of each cylinder.

1.Serious carbon deposits in the engine The most common cause of car shake is dirty throttle valves or excessive carbon deposits in fuel injectors. When there is too much carbon deposit inside the engine, the gasoline sprayed by the cold start fuel injector will be absorbed by the carbon deposit, resulting in the cold start mixture being too thin, making it difficult to start.

2.Ignition system problems Check the working condition of the spark plug, high-voltage wire and ignition coil, poor ignition system work and poor spark plug flashover condition will also lead to this kind of failure.

3.Air filter problem: The air filter is a necessary equipment to supply fresh air to the engine, if it is not cleaned in time or is blocked, it will affect the normal operation of the engine, causing problems such as idle shake and lack of refueling.

4.Engine control system problems: If the engine control system (e.g. ECU) fails, it can lead to problems with ignition, fuel**, cylinder pressure control, etc., causing idle shaking, weak refueling, etc.

If you are unable to overhaul it yourself, it is recommended to contact a professional car repair agency for inspection and repair in time.

Oil circuit problem: If there is a fault in the oil circuit, it will lead to insufficient fuel ** when idling and adding noise to take oil, and the situation of shaking and stalling will occur. 3.

Air filter problem: The air filter is a necessary equipment to supply fresh air to the engine, if it is not cleaned in time or is blocked, it will affect the normal operation of the engine, causing problems such as idle shake and lack of refueling. 4.

Engine control system problems: If the engine control system (e.g. ECU) fails, it can lead to problems with ignition, fuel**, cylinder pressure control, etc., causing idle shaking, weak refueling, etc. If you are unable to repair it yourself, it is recommended to contact a car repair agency specializing in bending and destroying the industry for inspection and maintenance in time.

The spark plug high-pressure package and high-voltage lines have all been replaced, the oil pump pressure, the fuel injector are no problem, and the cylinder pressure is no problem.

A fault code of an oxygen sensor was reported, and the same is true for changing the oxygen sensor.

Hello. If you have replaced the spark plug, high-pressure bag, and high-voltage line of the engine, and the oil pump pressure, fuel injector, cylinder pressure measurement and other related components have also been troubled, but the engine still has the problem of idle shake and weak acceleration, we can further rule out the following possible reasons:1

Air Flow Meter (MAF) Issues: Air Flow Meters are an important part of controlling engine fuel**, and if the sensor itself is damaged, loose, or damaged, it can lead to a lack of engine fuel**, causing idle jitter and weak acceleration. 2.

O2 Sensor Problem: The oxygen sensor is one of the most important components used to measure the oxygen content in the exhaust system, and if the sensor is damaged or damaged, it can lead to an imbalance in the fuel-to-fuel ratio, which can cause the engine to work abnormally. 3.

Idle control system problem: Idle control system is a system to control the engine speed in the engine idle state, if the system is resistant to pure failure, can cause the engine idle instability, shaking and other phenomena. If the above problems still cannot be solved after eliminating the above problems, it is recommended to consult a professional technician for further investigation and troubleshooting.

Summary. Focus on checking the engine ignition, this part is generally ignition is not good to occur this situation, the spark plug is not good, the cylinder line is not good or the high-pressure package is not good, the engine will shake, and the car will run weakly.

Hello, happy to answer your questions.

The speed of Jinbei can't go up, the engine is noisy, and there is no energy.

This situation is generally caused by the lack of cylinders in the blind spike grinding machine, check whether the ignition coil and spark plug of the engine are faulty? Is there any fault light on the meter?

There is no fault light on.

Will the engine shake when the car is in place? In the case of not being able to raise the speed, you still have to run to cause the engine to shake and not be able to raise the speed.

This situation is generally caused by poor ignition of the spark plug, take the spark plug out and check it, is the spark plug faulty?

When the fire is lit and the vehicle does not move, there will be a shaking of the socks, and when it reaches about 60, it is necessary to step on the accelerator and shout hard to slowly go up to about 80, and the sound of the car is very loud at that time.

In this case, one is that the spark plug is not good, and the other is that your clutch plate is worn, causing the vehicle to run weakly.

Focus on checking the engine ignition, this part is generally ignition is not good, the spark is not good, the cylinder line is not good or the high-pressure package is not stupid, the engine is shaking, and the car is not running hard.

2. Air flow problem: check whether the air filter is clean, if it is too dirty, it may lead to insufficient air flow. Clean or replace the air filter.

3. Ignition system problem: check whether the spark plug is clean and whether the gap is correct. If it is necessary to change or Xiangguo, replace the spark plug and adjust the gap.

4. Sensor failure: Check whether the sensor in the engine management system is working properly. If there is a fault, the sensor needs to be repaired or replaced.
