What is the reason why the car runs and eats a meal

Car jitter failure causes:

1. The positioning angle of the front wheel is inaccurate, and the toe is too large.

2. The tire pressure of the front tire is too high or too low or the tire is unbalanced due to repair and other reasons.

3. The front hub is deformed or the number of tire bolts is different.

4. The installation of transmission system parts is loose.

5. The transmission shaft is bent, the dynamic is unbalanced, and the front axle is deformed.

6. The shock absorber fails, and the front leaf spring rate is inconsistent; The frame is deformed, the willow nails are loose or the front axle is deformed.

Resolution. There are two situations of high-speed oscillation, one is that the oscillation becomes stronger with the increase of vehicle speed, and the other is that oscillation occurs at a higher speed and causes the steering wheel to swing.

1. Set up the drive axle first, add a safety plug plate to the front wheel, start the engine and gradually hang into the high-speed gear, so that the driving wheel reaches the final test oscillation speed, and the body and steering wheel shake at this time, which is the oscillation caused by the transmission system.

2. Check whether the positioning angles and toe of the front wheel meet the standard, and if it is inaccurate, it should be adjusted.

3. Set up the front axle test vehicle tires, check the static balance of the wheels and whether the tires are too deformed, and replace the good wheels for comparative testing if necessary.

4. Check whether the front axle and frame are deformed, and check whether the transmission shaft is deformed.

5. Whether the chassis is loose and whether the ball head changes.

6. Check the front leaf spring rate, the efficiency of the shock absorber and whether the spring bracket willow nails are loose if they need to be replaced.

<> the car found that the engine shook after starting, one by one, suspected that there was a problem with the quality of the oil products, in fact, it is not the case, the quality of the oil sold by Sinopec gas stations has been inspected and checked at all levels, and the quality of the oil products is guaranteed, and it can be used boldly and with confidence

It is generally the case that there is a problem with the ignition system, such as spark plugs, cylinder lines, etc.

Poor oil circuits can also have this problem, such as clogged injectors.

It may also be caused by excessive carbon deposits, focus on checking the carbon deposits of the throttle body, if there is carbon deposits, clean the carbon deposits first and observe them in the test run.

If the vehicle is driving in the city for a long time, it is recommended to wash the throttle body every 15,000 kilometers.

It is a problem with the oil circuit, which may be the reason for the poor oil supply, or it may be the reason for the lack of power caused by the wrong gear you use.

Is it too oily and not smooth. Check it out. Clean it up.

The simplest and most economical solution is to replace the spark plugs and gasoline grid.

No, I can't go to the repair shop.

The reason for the frustration in the vehicle is that there is more carbon accumulation in the first throttle, fuel injector, and intake tract; second, the quality of fuel is unqualified and the combustion is insufficient; The third spark plug, ignition coil and other faults, resulting in a lack of cylinders, etc. In most cases, the driving frustration of the vehicle is caused by the gasoline burning poorly inside the engine.

The frustration of driving the vehicle is the cause of **.

There is a frustration in the car driving, and the engine must not get rid of the relationship. The ignition, air intake, and fuel injector jointly determine the combustion of fuel, which is also the power of the engine. At this time, if the air intake becomes low, the ignition becomes weaker, or the oil sprayed becomes less, the power will be insufficient, and there will be a sense of frustration.

If the engine has too much carbon deposit, which causes the vehicle to feel frustrated while driving, you can check whether the spark plug of the car needs to be replaced and whether the throttle valve needs to be cleaned. Generally, in addition to frustration, excessive carbon deposition is easy to cause the power of the engine to not keep up, if the power can not keep up, then it is likely to be the cause of excessive carbon deposition in the engine.

If the automatic transmission model malfunctions the driving computer, there may also be frustration, because the frustration is caused by the mismatch between the engine and the vehicle speed, in the automatic transmission, consciously release the throttle before shifting, the gearbox will respond immediately and automatically complete the shift, and then step on the accelerator to enter the higher gear. In this process, the computer is also like a human, if the response is not strong, or if there is a fragment, there will be problems.

It is also possible that there is sludge in the transmission oil, and the oil channel in the transmission will be blocked by circulating in the gearbox, which will lead to a series of transmission problems such as high temperature, impact, and skidding in the gearbox for a long time.

Hello, happy to answer your questions.

This depends on whether you are a manual transmission or an automatic transmission, if it is a manual transmission model, you must have chosen too high a gear, which will cause the vehicle to be out of gear, if you are an automatic transmission car, then you need to check whether there is a problem with the gearbox, this common reason is the failure of the gearbox inside.

Questions. The van was not added up at a low speed, and the kindergarten was only able to get up with a huge red and yellow.

The van was not added up at a low speed, and the kindergarten was only able to get up with a huge red and yellow.

What do you mean? Questions.

When the van is driving at low speed, you can't add oil, step on the clutch, and the big throttle will be good to coax a few times to go.

It is recommended that you check that the fuel pressure of the engine is normal and replace the spark plugs.

Questions. The spark plug looked at it, and it was good to see.

Then test the fuel pressure and clean the injectors.

Questions. Could it be the spark plug?

Didn't you say the spark plug looks good? How about jumping over the fire when you try to ignite it?

Questions. When I got up, I hit it.

So it's best to measure the fuel pressure, it may be that the oil circuit is blocked.

1. The gasoline filter is clogged and needs to be replaced.

2. There is too much carbon accumulation on the throttle, just clean it.

3. The fuel injector should be cleaned.

4. The spark plug needs to be replaced.

5. The oil pressure caused by poor fuel quality cannot be reached.

The order of inspection is generally the throttle, spark plug, steam filter and fuel injector.

Extended Materials. "Six-character" diagnostic method In the process of troubleshooting, it is necessary to use the "six-character" diagnostic method

1. Learn about the situation from the driver;

2. Look, observe the faulty vehicle, including the exhaust and lubricating oil;

3. Listen, listen to what kind of abnormal noise occurs when the car is running;

4. Sniff, sniff out where the faulty vehicle has any peculiar smell;

5. Touch, touch the heating, vibration, air leakage, oil leakage, water leakage and other conditions of the vehicle, as well as the flexibility of the mechanism;

6. Test, verify the possible faults and fault parts through the test.

When eliminating faults, according to the phenomenon of the fault, the necessary testing instruments should be used to analyze the location of the fault, and the cause of the fault should be found out according to the steps of easy and then difficult, simple and then complex, bright and dark, first circuit and then oil circuit, and then eliminated.

One meal, it may be that the carbon deposits are more serious, you go to check it and clean the carbon deposits.

Hope, thank you.

It is inseparable from the problems of engine oil circuit, ignition, and air intake, which may be due to the fact that there is sludge in the transmission oil circulating in the gearbox, blocking the oil passage in the valve body, and the problem of frustration will occur, which will lead to a series of gearbox problems such as high temperature, impact, and slippage of the gearbox for a long time.

If the car accelerates with a sense of a meal, then it must be a lack of fuel. This feeling will occur when the car cannot be refueled.

The phenomenon of a car meal is mainly common in cars with manual transmissions. Because the manual transmission needs to change gears by itself, and in the process of driving, if the speed and gear do not match, there will be a situation of one meal.

There may be two aspects of the car acceleration in the middle of a pause.

First, the acceleration is too fast, resulting in a temporary jam of the engine, which can return to normal after increasing the speed.

The second is that there is a problem with the spark plug, which may be partially blocked.

There are the following reasons:

1. Gasoline filter.

2. The throttle should be cleaned.

3. The fuel injector should be cleaned.

4. The spark plug needs to be replaced.

You can decide which to check first according to the maintenance of your car, for example, the gasoline filter is not changed for a long time, and whether there is no oil with guaranteed quality during the period, the priority will be put to the back, and you can generally consider checking the order of throttle, spark plug, steam filter, and fuel injector.

1. Under the action of long-term torsional fatigue and impact force, the half shaft of the car is prone to bending, twisting and breaking, as well as spline tooth wear or torsion, which leads to regular shaking of the front of the car when it accelerates to a certain speed range, and the shake disappears or decreases after releasing the accelerator.

2. When the car is on the gas pedal, then the problem is likely to be the engine operation, the engine needs to ensure that the work needs to have sufficient air, sufficient gasoline and a good ignition system, any problem will lead to the engine jitter.

First, the clutch may be too fast, if you manually remember to put half of the clutch half, the car starts to move, you can step on the accelerator and then slowly release the clutch, the second throttle may have to be cleaned, the third if you are starting after driving a little distance, suddenly feel that the car is a meal, the throttle is a little deeper, this feeling disappears, it is because this is the electronic throttle, the accelerator you stepped on in front of the oil has actually burned out, the electronic throttle response is slow, you step on it again, the oil has not yet begun to burn, such a situation occursIn this case, remember that the throttle should not be too big or too small, just be smooth.

It may be that the clutch is loosened too quickly, or it may be caused by different tire pressures.

Check the oil pressure of the gasoline pump of the vehicle in the middle of the vehicle one by one, if the oil pressure is not normal, this phenomenon will occur, you also need to use the diagnostic computer to read the fault code, to see if the vehicle has a fire phenomenon, if the ignition efficiency of the spark plug is not good, resulting in engine fire, the vehicle will shake, there is also a possibility that the gearbox is faulty, the internal combination of the gearbox is not in place, it will also cause this phenomenon, this situation first replace the transmission oil using the diagnostic computer to read the fault, according to the prompt of the fault code for maintenance.

Bicycle? Electric car? Car? Big trucks? Van?Tricycle?Oxcart?

Stepping on the accelerator is because the half shaft of the car is prone to bending, twisting and breaking, as well as spline tooth wear or twisting and other faults under the action of long-term torsional fatigue and impact force, which leads to the car to accelerate in a certain speed range, the front of the car will have regular shaking, and the shaking will disappear or reduce after releasing the accelerator.

Since the car is on the gas pedal for a while, then the problem is likely to be the engine operation, the engine needs to ensure that the work needs to have enough air, sufficient gasoline and a good ignition system, any problem will lead to the engine jitter. The engine needs to have enough air to ensure that it works, and if the air intake system is leaking or blocked, then when the car is on the accelerator, there will be a situation of acceleration and shaking.

Hello, the car will be paused in the acceleration of the accelerator, it may be caused by carbon deposition in the car engine, It is recommended that you check the spark plug of the car to see if it needs to be replaced, and whether the throttle valve needs to be cleaned.

If there is a sense of frustration when the car accelerates, it is necessary to check whether the lower throttle is normal, whether the spark plug is working normally, whether the fuel injection volume of the injector is normal, and whether the gasoline quality is normal.

It may be a lack of cylinders, and there will be a meal when my car is refueled, and it is said that it is a 2-cylinder cylinder missing after testing with a detection computer, and you can drive the car to the repair shop to test it. If you lack a cylinder, you need to replace the spark plug, see that your spark plug has also been replaced, and the ones that should be replaced have been replaced, then you can find a senior and skilled master to help you take a look.

It may be caused by carbon build-up in the car's engine, so it is recommended that you check the spark plug of the car to see if it needs to be replaced and if the throttle valve needs to be cleaned. I hope my answer will help you.

1. Check the throttle.

2. Check the fuel injector.

3. Check the air intake.

4. Check the spark plugs.

5. The main reasons for checking the ignition coil: 1. Long-term short-distance driving, 2. The quality of air and oil is not good, and 3. The car has been running for a long time.

It may be that the oil or air circuit is not smooth, check whether the fuel filter and air filter have not been changed for too long.

Ignition coil, spark plug, if you can do it yourself, if you are sure that the ignition coil is broken, you can buy a few rubber sleeves to replace it, there is no need to replace the entire ignition.

Check that the variable intake manifold is working properly, in the solenoid valve with variable valve timing.

Has the reason been found?My car is the same, with a manual supercharged engine, and the car is a year and a half!

If you want the 4S store to check the ignition waveform with an oscilloscope, there is a problem with the ignition coil.

Check the oil pressure of the gasoline pump of the vehicle in the middle of the vehicle one by one, if the oil pressure is not normal, this phenomenon will occur, you also need to use the diagnostic computer to read the fault code, to see if the vehicle has a fire phenomenon, if the ignition efficiency of the spark plug is not good, resulting in engine fire, the vehicle will shake, there is also a possibility that the gearbox is faulty, the internal combination of the gearbox is not in place, it will also cause this phenomenon, this situation first replace the transmission oil using the diagnostic computer to read the fault, according to the prompt of the fault code for maintenance.
