Ask for help, after changing the oil, I obviously feel the idle vibration

Is it too much oil.

It has little to do with engine oil. First of all, the most common cause of car shake is the throttle.

Too dirty or too much carbon build-up in the injector. When carbon deposits inside the engine.

Too much, cold start.

The gasoline emitted by the injector is absorbed by the carbon deposits, resulting in a diluted mixture for the cold start, making it difficult to start.

In this case, only when the gasoline absorbed by carbon deposit is saturated, it is easy to get on the car, and the gasoline adsorbed on the carbon deposit will be sucked into the cylinder by the vacuum suction of the engine after landing, and the mixture becomes thicker, and the combustible mixture of the engine is dilute and thick, resulting in idle speed after cold start.

Dithering. At this time, the owner should clean the oil circuit, and at the same time, he should also check whether the idle motor has carbon deposits and should be cleaned.

If it's not the engine that is causing the car to idle and shake, then you should check the spark plugs.

The working condition of the high-voltage wire and ignition coil, the poor working condition of the ignition system, and the poor condition of the spark plug flashover will also lead to this kind of fault phenomenon. When it is determined that the main cause of idle jitter in the ignition system is the main cause, the spark plug should be checked for excessive carbon build-up and the spark plug replaced.

If you have cleaned up 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 to continue 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 poor, the body will shake. At this point, the oil pressure should be checked and, if necessary, the parts should be replaced.

It has little to do with engine oil.

Engine idle jitter is caused by insufficient power output when running at low speeds, and there are many possible triggers, such as poor oil circuits, sensor (intake pressure, air flow, etc.) signal failure, engine computer failure, ignition system wiring failure, etc.

It is recommended that you find an experienced master and rule out the screening one by one.

1. Use fully synthetic engine oil, such as 5w-40, but the cost will be twice as high as 10w-30. But the effect is obvious, and it is easy to have a sense of dependence.

2. Check the engine spark plug model and aging, ignition matching problem 3, ignition coil failure, cylinder loss.

4. Maintain clear fuel injectors, throttles and other parts.

Please troubleshoot at once.

There is a certain relationship! I've also seen the oil change and everything works fine, as long as it stops! At the start, it will fly ..The same goes for changing the oil pump! It's just a diesel engine!

It doesn't have much to do with it, it has to do with the speed control system.

After changing the oil, the engine idle shakes heavily. In general, the model of the oil does not match. In this case, the oil should be drained and then re-added with the oil that matches the engine model.

Generally, motor oil used in automobiles is fixed. You can use a less viscous oil in the summer and a higher viscosity oil in the winter. When changing the oil of the car, it must be changed according to the type of oil marked on the car instruction manual to prevent engine problems caused by the mismatch of the oil residue.

There are many reasons for engine idle jitter, including serious carbon deposits, poor fuel quality, and unsuitable engine temperatures.

The following are specified:

1.Serious engine carbon deposits: Engine carbon deposits can clog the engine's oil system, making the fuel unable to burn properly, resulting in engine idle shaking. In this situation, the carbon deposits of the engine need to be cleaned up in time.

2.Low fuel quality: If the added fuel quality is too low, it will also cause problems such as engine idle shake and increased fuel consumption. In this case, high-quality fuel should be replaced.

3.The engine temperature is not suitable: it is normal for the engine to idle and shake when the car is cold started. When the engine temperature rises to the right range, the jitter problem is automatically eliminated.

What is the reason for the severe idle shaking after changing the oil?

When changing the oil, the engine idle shakes a lot, which usually means that the oil model does not match. In this case, the oil should be released and then the oil that matches the engine model should be added again. Generally speaking, the oil used in the car is fixed, the oil with lower viscosity can be used in the summer, and the oil with higher viscosity can be used in the winter.

When changing the engine oil of the car, it is necessary to change the oil model marked on the instruction manual of the car to prevent problems with the engine engine due to the mismatch of the engine oil. There are many reasons for the idle speed shake of the automobile engine, including serious carbon deposits, poor fuel quality, and inappropriate engine temperature, etc., which are explained in detail below. 1.

Serious engine carbon deposits: Engine carbon deposits can clog the engine's oil system, making the fuel unable to burn normally, resulting in engine idle shaking. This situation requires timely cleaning of engine carbon deposits.

2.Poor fuel quality: If the added fuel quality is too low, it will also cause problems such as engine idle shake and increased fuel consumption.

In this case, high-quality fuel should be replaced. 3.The engine temperature is not suitable:

When the car is started cold, the engine idle shakes normally. When the engine temperature rises to the right range, the jitter problem will be eliminated automatically.

After changing the oil and changing the dress, the idle speed shake is serious. It must be bad burning. Nothing more than oil, air and ignition.

It is recommended to go to a 4S shop or a professional repair shop for testing. Engine oil, i.e., nuclear engine lubricating oil, can lubricate to reduce wear, assist cooling, seal and prevent leakage, anti-rust and anti-corrosion, shock absorption and cushioning, etc. It is called the "blood" of the car.

There are three types of motor oil:1. Synthetic oil total.

Severe idle jitter after an oil change. It must be bad burning. Nothing more than mountain oil, air and ignition. It is recommended to go to a 4S shop or a professional repair shop for testing.

Engine oil, i.e. engine lubricating oil, can lubricate to reduce wear, assist cooling, seal leakage, rust and corrosion, shock absorption, cushioning, etc. It is called the "blood" of the car. There are three types of motor oils:

1。Total amount of synthetic oil2. Semi-synthetic oil 3.

Mineral oil. Fully synthetic oils are the highest grade of engine oils. As the name suggests, it is also the highest among motor oils, and its advantage is that the cold start is smoother, especially in the Northeast region. Save more fuel; Long oil change intervals; Extend the service life of the engine and reduce the maintenance rate; The engine block is cleaner due to the excellent cleanliness of synthetic oil.

Semi-synthetic oils, which are somewhere between synthetic and mineral oils, are a good by-product. Of course, it's somewhere between mineral oil and synthetic motor oil.

Mineral oil generally refers to mined and pre-processed** and is relatively low in engine oils**.

In general:1. Synthetic oil is used for turbocharged engines, synthetic oil is used for models with low ambient temperatures, and synthetic oil is used for high-end models. 2.Semi-synthetic oil is used for mid-range cars. 3.For low-end cars, consider the cost of the car and choose mineral oil.

The replacement cycle of three types of oil, one year or 10,000 km for synthetic oil, half a year or 7,500 km for semi-synthetic oil, and half a year or 5,000 km for mineral oil.

What is the cause of engine shake after changing oil.

The engine shakes after an oil change may be because the new oil is not suitable for the car, the oil is not **, there are many impurities, and the oil is added too much or too little.

If the viscosity of the new oil is not suitable for the car, the injectors may clog, resulting in inconsistent injectors injecting, inconsistent cylinder work, and engine shaking. The solution is to take it away and wash it clean.

If the oil is not **, it contains a lot of impurities, which will lead to excessive carbon deposit. After a period of use, the throttle, idle valve and air intake will be clogged by carbon and grease, and the air intake will be poor, affecting idle stability and jitter. The above parts can be solved by checking and cleaning with a cleaning agent, and there is no need to remove and clean.

The engine cylinders have two scales. Too much or too little oil can cause the engine to shake. Unscrew the cap and see if the liquid level is within range. If not, tweak it. If there is any, take out a little. If you have less, you will add it.

When buying engine oil, you should look for ** and check whether the oil model is suitable for your car. If you are afraid of buying a fake, you can go to the 4S store to change the oil, which is generally **.
