Buick Yinglang cold car gear on the engine shake and noise

After starting the car in the cold, wait for the idle speed to drop down, and then hang it to try, the idle speed of the cold car is high, and it is easy to appear duang when the gear is in gear

If the vehicle has not been started for a long time, it is normal for such a situation to occur, and if it is often driven, it is the shaking of the engine, and there is generally no problem. If it often appears, go to the 4S store to do a computer test.

There are a few points in this, 1Lack of fire! Yinglang's common problem, spark plugs, ignition coils, or fuel injectors, ignition coils are the majority.

2. Oil problem, less oil, or too dirty. 3. The lower guard plate is rubbed with the engine! I suggest you go get it overhauled.

If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello This phenomenon is usually caused by damage to the fulcrum of the machine or the engine guard plate is too close to the engine.

I hope mine is helpful to you I wish you a pleasant car If you still have questions, please invite [If you have any questions about the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, this advice to clean the throttle and engine, if my answer is helpful to you, please set it to.

Hello. Check the throttle, it is caused by the inappropriate ratio of the mixture. Hope it helps.

There are generally several reasons for engine idle shaking, and the most common reason for car shaking caused by serious engine carbon deposition is that the throttle valve is too dirty or the fuel injector is too much carbon, because the gasoline adsorbed on the carbon deposit after the car is sucked into the cylinder by the engine for combustion, and the combustible mixture of the engine is dilute and thick, resulting in idle shaking after cold start. Solution: Siyoupu cleans the oil circuit and checks whether the idle motor has carbon deposits and should be cleaned.

Summary. If this phenomenon occurs in the automatic transmission model, this is a normal phenomenon, because after this gear is hooked, the vehicle does not exercise the engine, and needs to provide power to the gearbox. It requires a lot of torque and power output, so his voice will be a little louder.

This automatic transmission will have this phenomenon in most models, if the vehicle kilometers exceed this 60,000 kilometers. There is also a relatively large number of kilometers, and the power performance of the engine decreases, so the sound is relatively large after this gear is hooked. Then it is necessary to clean the throttle valve and fuel injector, replace the spark plug, and check that the engine cylinder has more carbon, which also needs to be cleaned.

The engine is quiet when it starts, but it is loud when the rear gear is engaged.

See. See.

It's more than 60,000 open.

Not before.

It's 60,000.

In this case, it means that these aspects of the engine need to be cleaned and inspected.

Summary. Hello dear, the reason for the loud start of the old Yinglang cold car is that the torque and power output of the engine after the cold car start are insufficient, and a lot of power and torque output are required when the gear is driven, so there will be this phenomenon. As long as there is no such phenomenon in the case of a hot car, it doesn't matter much, and it can be used normally.

This is mainly in the case of a cold car, and the torque and power output of the engine are insufficient. It is necessary to clean the throttle valve and fuel injector, replace the spark plug, clean the three-way catalytic converter, and check that the engine cylinder has more low carbon, which also needs to be cleaned. <>

The old Yinglang cold car started the gear and started with a loud noise.

Hello! Hello dear, the reason for the loud start of the old Yinglang cold car is that the torque and power output of the engine after the cold car start are insufficient, and it takes a lot of power and torque output when the gear is driven, so there will be this phenomenon. As long as there is no such phenomenon in the case of a hot car, it doesn't matter much, and mindfulness can be used regularly.

This is mainly in the case of a cold car, and the torque and power output of the engine are insufficient. It is necessary to clean the throttle valve and fuel injector, replace the spark plug, clean the three-way catalytic converter, and check that the engine cylinder has more low carbon, which also needs to be cleaned. <>

The Qashqai cold car will bang when it is in gear, and it will be fine in a while!

Further information: Buick Yinglang is a car under SAIC-GM. The all-new Yinglang adheres to the design language of Buick's "dynamic and smooth", draws on the classic elements of the Riviera concept car, and the body shape is sporty and stable, presenting a new Yinglang atmosphere, simple, elegant and dynamic style.

The combination of the new flying wing car fiber milled chrome closed bucket grille, HEISE piano vertical grille and high-gloss chrome flying wing grille allows the visual center of the front to naturally focus on the logo.

No gear, no sound!

Dear, there's something wrong with your gearer. <>

Broken gear? Cold car history hanging gear boom? Don't want to think about it for a while?

Dear, your gear will ring, and if you don't hang the gear, it won't sound and your gear has a lot to do with it. <>

Summary. Hello friends, the old Buick Yinglang is in gear, and the causes and treatment methods related to engine shake are as follows. First, the phenomenon caused by excessive carbon deposition inside the engine or lack of cylinders needs to be cleaned up, and the ignition coil and spark plug should be checked.

The second situation is caused by a problem with the fixed claw pads of the vehicle engine or gearbox, and this phenomenon needs to be checked to fix the claw pads. The third situation is that there is a problem with the relevant sensor, which should check the relevant intake pressure sensor of the vehicle.

Hello, I want to consult, my old Buick Yinglang automatic, hanging D gear engine is like panting, a little shaking, go to the repair shop to replace the limbs are disassembled, now the gear and other historical red light or shaking, please ask what is broken, what is the reason, I really Qinyan is no way to ask you, hello friend, the old Buick Yinglang gear, engine shake related causes and treatment methods are as follows. First, the phenomenon caused by excessive carbon deposition inside the engine or lack of cylinders needs to be cleaned up, and the ignition coil and spark plug should be checked. The second situation is caused by a problem with the fixed claw pad of the vehicle engine or gearbox, which needs to be checked to fix the claw pad.

In the third case, there is a problem with the relevant sensor of the slag macro, and it is necessary to check the relevant intake pressure sensor of the vehicle to eliminate this.

What you said, the repair shop has replaced it for me, and the charcoal has been washed, and now it's time to hang D gear or wait for a red light, and the engine is shaking all at once.

The engine looked like it was about to turn off and then turn on again.

The vehicle is under load, and the idle speed is obviously unstable. , and the vehicle doesn't have any breakdowns**, right?

Then this one is recommended to replace the wastegas valve.

There are no fault codes, the spark plugs, ignition coils, air intake sensors, charcoal deposits are washed, and the idle speed meter does not move, which is the shaking of the gear engine.

Then take a look at the data flow related to the vehicle engine, the intake simple impulse flow data and the long-term and short-term fuel correction data when the idle speed is unstable.

I found someone who got a computer, showed it to me, and repaired it, and it's still like this.

According to what you said, basically everything that should be repaired has been repaired, and everything that should be replaced has been replaced.

Has the canister solenoid valve been replaced?

The reasons for the abnormal noise of the cold start engine are as follows: 1. The hydraulic tappet is worn and aged. 2. The valve clearance is too large.

3. The throttle is too dirty. 4. The working sound of the solenoid valve of the carbon canister. 5. The three-way catalytic converter expands when heated.

6. The timing part is abnormal. 7. The sound of the air conditioner belt rubbing. 8. The exhaust valve of the fuel tank is not working well.

9. There is an impact on the fluid inside the reflux pump. 10. There is a partial blockage inside the fuel filter.

1. The engine has abnormal noise symptoms: there are more possibilities for abnormal noise in the engine compartment, and most people also judge that it is the abnormal noise of the engine compartment based on the sound, which is usually a metal screeching sound or a howling sound. Workaround:

Abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment. Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.

It should be reminded that if it is an abnormal noise in the engine, most of the owners will not be able to solve it by themselves, and it is best to send it to the factory for maintenance.

2. Abnormal noise symptoms in the gearbox: If there is a "rustle" sound inside the gearbox during driving, and there is no world match after stepping on the clutch simple branch return or accelerator, there will be a sound similar to whistling when changing gears. Workaround:

There are many transmission parts, and the cause of the sound is also more complex, so it should be noted in the analysis and judgment: whether it is related to the speed of the special stop, such as some planetary teeth sound more obvious at about 50km h. Whether it is related to certain gears, which is very important for judging the failure of the transmission, if a certain gear sounds, it must be related to the components that affect the transmission of the gear; If all gears sound, it is often a common meshing shaft failure or a lack of oil in the transmission.

Whether it is related to specific actions, such as increasing and decreasing gears, starting, rapid acceleration, sharp deceleration, turning, etc., are effective means to judge abnormal noise, among them, changing speed and direction are particularly important for judging the rear axle fault. If the abnormal noise of the transmission is obvious, it is recommended to send it to a professional repair shop to check the faulty parts, and then replace them.

3. Symptoms of abnormal noise in wear: There are always some abnormal noises in a certain part of the body when driving and stepping on the accelerator or brake, the sound is not loud, and it does not affect normal driving, but it always makes people worry that there is a fault. Workaround:

The abnormal noise of the door is mainly caused by the lack of lubrication, but it is necessary to determine whether it is the position of the door hinge or the glass regulator, door lock mechanism, handle mechanism, etc. inside the door. In the case of door hinges or limiters, special door hinges and slide grease can be used, while special door attachment grease is used for lubrication of glass regulators, door locking mechanisms, handle mechanisms, etc. inside the door. In terms of brand selection, try to choose the commonly used brands in 4S stores, such as German Marty, Kluber, Tiger Head Hotolube, Fox, etc.

It is not advisable to use engine oil or ordinary butter, it will freeze in winter, and the harmful smell will affect your health.

Intermittent jitter. It may be caused by dirty throttle or too much carbon in the intake pipe and too low idle speed, or the ignition system has a lack of fire (bad spark plug, poor ignition coil), poor oil, etc., which is related to the working state of the engine.

What to do if Buick Yinglang 15 automatic gear shake Buick Yinglang 15 automatic gear shake, the details are as follows:

1. The jitter comes from the gearbox, because the gear is in D gear, which is in the state of pure connection of power. The power of the engine is transmitted to the gearbox, which passes through the propeller shaft to the wheels. I was supposed to move forward, but the brakes were stepped on and I couldn't walk.

Therefore, the gearbox has been holding back a force, and it will shake.

2. The continuous jitter is obvious in the D gear. It may be that the engine, gearbox, exhaust pipe spine and other interference with the bottom plate or body or the aging and cracking of the shock absorbing glue, resulting in the normal vibration of the engine directly out of the car, Zheng Rui The most common is that the gap between the lower part of the engine and the bottom plate is too small, and a certain gap can be maintained in neutral.

3. Intermittent jitter. It may be caused by dirty throttle or excessive carbon deposition in the intake pipe and too low idle speed, or the ignition system has a lack of fire (bad spark plugs, poor ignition coils), poor oil, etc., which is related to the working state of the engine.
