The reason why the car stalls at low gear, and the reason why the automatic transmission stalls at l

The problem of cold start and shutdown involves many aspects, here are a few reasons that can be encountered in daily cars:

2. There is too much carbon accumulation on the throttle, which is also the main reason for the problems such as unstable idling and stalling of the car. Go to a professional repair shop or 4S shop to clean the throttle.

3. The pressure of the gasoline pump is low or the fault is easy to cause the flameout due to the lack of oil.

4. Due to the long-term parking of the vehicle, the oil is viscous and the car stalls, this phenomenon is not much of a problem, and the car can be heated after the fire.

The problem of stalling in most people's minds only manual transmission models will appear, and we all know that theoretically, the automatic transmission will not turn off by itself, unless there is no fuel, the engine is flooded, or check the car's oil circuit and circuit, fuel injector and throttle.

In this case, it is necessary to do the following:

1. Turn on the double flashing lights.

2. Step on the brakes and stop as soon as possible.

3. After stopping, hang the gear lever into the P gear and re-turn the key to start the engine 4. After the ignition occurs, go to the 4S shop for inspection as soon as possible.

In fact, there is no special skill in the treatment method, the first is to turn on the double flashing lights at the moment of finding the problem, in order to remind the rear car that there is a problem, and the second is to step on the brakes to stop the car as soon as possible, and then turn the key center to start.

The car can be started and used normally, only occasionally low-speed shutdown means that the ignition system is good, the key is to look at the throttle and idle valve, you should clean it in the test to see the effect.

There are several main reasons for automatic transmission to stall at low speed. 1. Long-term parking leads to lubrication or circuit problems, and the oil circuit is not smooth, which can easily lead to halfway flameout. Second, the fault cause of the car stalling in the idle state is mainly due to too much dust in the air, the engine in the operation of the idle motor valve core and throttle seat deposited a lot of dirt, when the dirt accumulation is too much, the state town engine will appear idle too low, idle stability is poor, there will be idle stall when driving.

The solution to this problem is as simple as cleaning the idle motor. 3. Thoroughly clean the oil circuit, including the fuel injector, the closed round eggplant valve, the fuel tank, etc., the automatic low-speed flameout may be due to the quality of the added oil, too much grease, the oil circuit is blocked, and the oil attack is not smooth. Fourth, the use of high-standard, high-quality and qualified fuel.

Fifth, for novices, turning off halfway is not a new topic, and the main elimination method is to improve their driving skills after rapid running-in.

Sudden stalling in low-speed driving may be due to the blockage of the fuel injector, and the atomization effect of the fuel injector hall is poor after the fuel injector is blocked, and the engine may cause stalling if it is not working properly; If the oil pressure is insufficient or the oil pump is faulty, it will also lead to flameout; At this time, you should try to grasp the control direction and pull over for inspection.

What to do if the ignition is turned off during low-speed driving?

1. Don't panic, stabilize the steering wheel, drag the brake according to the situation, and you can choose to pull over. For manual transmissions, you can try removing the clutch, putting the gear lever into the corresponding gear according to the speed, and then loosening the clutch to use the speed to drive the engine up.

2. If the ignition is turned off due to deceleration and braking while driving, you can take stupid measures to increase the braking strength, and pay attention to the surrounding situation at the same time, and there is a chance to change lanes to bypass the obstacles in front.

If conditions permit, you can put in the corresponding gear after the low-speed shutdown and start the ignition again, and use the movement of the vehicle to drive the engine.

In the process of low-speed driving, the sudden stalling of the car is due to the lack of gasoline in the car, or the failure of the starting equipment, so it is best to recommend that the car be repaired, and replace the bad parts when the reedan and the chaotic tung are replaced to ensure its safe driving.

The reason why the car suddenly stalls at low speed is because their big rent is too low and the fuel intake is too small.

When the car suddenly turns off at low speed, the first thing to look at is how much fuel leaks from the dashboard? It is possible that there is a problem with the oil circuit and the oil supply is not available, so the return stop will automatically turn off.

What is the reason for the sudden shutdown of the car at low speed? I think it's the engine that has a problem, you should lean on the side of the road to check it, if you want to be slow, it's not easy to go wrong.

Sudden flameout may cause power and oil outages; The power outage may be a circuit problem or a PC version; If the oil is cut off, you need to check whether the fuel pressure will be discharged.

What is the cause of a sudden stall in a car while driving at low speed? I think there's something wrong with the car, so check it out.

Hello 1The engine is out of fuel;

engine inlet sparrow cover;

The use of low-quality fuel causes the engine to stall due to carbon deposit;

The main reason for the stalling of the new car is that the driving skills are not skilled enough, and another possibility is the problem of the car engine or oil circuit, but for the new car of Song Suilu, the problem of the engine itself is less likely, and most of the reason is the problem of the oil circuit. How to deal with the low-speed shutdown of the automatic transmission: The first is to turn on the double flashing lights at the moment of finding the problem to remind the rear car that there is a problem, and then step on the brakes to stop the car as soon as possible, and then turn the key center to start.

One is that the oil circuit is not smooth, the power is insufficient, and the other is that there may be protective flameout.

1. The automatic transmission model will not easily stall, while the manual transmission model may often stall due to the low driving level. However, it is not excluded that automatic transmission cars will not stall, and the main reason is that the engine stalls due to carbon accumulation due to the use of inferior fuel (many gas stations sell impure oil for profiteering).

2. In addition, the reason for the stalling of the new car (automatic transmission) is mainly caused by the lack of skillful driving skills, and another possibility is the problem of the car engine or the oil circuit, but for the new car, the problem of the engine itself is less likely, and most of the reason is the problem of the oil circuit.

3. Finally, for old models, the reason for the stalling is not enough driving skills, that is, the use of substandard oil to make the engine collect carbon and other causes of stalling.

Troubleshooting method of automatic transmission car stalling: Usually pay attention to the place: For the phenomenon of automatic transmission car stalling, it is mainly caused by the use of inferior fuel.

One is to go to a regular larger gas station to add high-grade oil, such as using 97 gasoline, although it is a lot more expensive, but it can ensure a longer life of the car and good power in operation. However, some car owners are greedy for cheap and 90 oil, although it is lower, but there may be problems in the future.

The second is to go to a large qualified gas station to refuel! Practical operation: Hold the steering wheel with your left hand to stabilize the direction (because there is no power assist, so you must stabilize it hard), press the brake with your right foot to reduce the speed as much as possible, and then quickly hit the AT gear to N gear, (Note:

Re-ignition must be in N gear during the march, not D r P and other gears, otherwise, the car either does not ignite, or the car gearbox will be damaged), and then the key is set back one square, and then re-ignition, and then the AT gear is restored to D gear normal driving.

Manual transmission car shutdown troubleshooting method:

1. For novices, turning off the engine halfway is not a new topic, and the main elimination method is to quickly run in and improve their driving skills.

2. Use high-standard, high-quality and qualified fuel.

3. Clean the oil circuit thoroughly, including fuel injectors, throttle valves, fuel tanks, etc. It may be that the quality of the oil you add is not up to standard, there is too much grease, the oil path is blocked, and the oil attack is not smooth.

4. The main reason for the failure of the car to stall in the idle state is due to too much dust in the air, and there is a lot of dirt deposited at the valve core of the idle motor and the throttle seat when the engine is running. The solution to this problem is simple: just clean the idle motor.

5. Whether the oil circuit is smooth or not, which is also easy to cause the engine to stall halfway.

6. Due to the price of oil, coupled with the return of many people's hobbies - cycling, walking to work has increased, so new cars have been parked for a long time and are not used. In fact, it is important not to park it for a long time. In case of a long parking time, you should do a thorough maintenance before re-use, change the oil, filter, etc., and check the fuel, electrical circuit, etc. as appropriate.

It is possible that the vehicle has been parked for a long time and there is a problem with the lubrication or electrical circuitry.

1. Inside the engine.

Excessive wear and tear inside the engine, cylinder pressure, excessive carbon (including valves), improper maintenance (or untimely), etc., can easily cause abnormal working conditions and lead to flameout.

2. Individual parts are damaged.

Damage to internal parts of the engine, damage to external parts (such as various idlers, excessive wear, jamming; A belt breaks, etc.), resulting in flameout.

3. The water temperature is abnormal.

The water temperature is too high, the heat dissipation electronic fan does not rotate or rotates abnormally, etc., resulting in flameout. Tires, brakes and other chassis systems: brake locking, tire leakage (or no air), bearing jamming (poor lubrication or its own quality failure), etc.

If the engine sometimes stalls when idling, and it is normal after restarting, it is called "intermittent idle stalling", this fault is very difficult to investigate, and there are many reasons for it, and various parts or circuits are not completely damaged, and the more headache is that the engine can be restarted after the engine occasionally stalls and can return to normal.

So even if the engine idles off due to a sensor, the engine ECU will consider this phenomenon not to be a fault.

It may be that the air-fuel ratio is too high, you can go to a 4S shop or repair shop to adjust it. Because after the air-fuel ratio is high, the oil burns more slowly, and the strength is not enough, so you need to step on the accelerator quickly to refuel. In this case, it is generally enough to adjust the air-fuel ratio.

If the cause is engine shake when parking after driving, it may be caused by excessive carbon accumulation in the throttle valve, idle motor, intake valve, intake pipe, combustion chamber, spark plug, fuel injector, etc. Because these carbon deposits will block the idle channel, the idle motor will be stuck or beyond its adjustment range, which will cause low idling, unstable idling, oil collection and vehicle extinguishment. It is also necessary to pay attention to check whether there is a fault in the carbon canister, which causes the mixture to be in a thickened state when the engine is working, resulting in the mixture being too thick when driving at low speeds, which leads to the stalling of the vehicle after the oil is sheathed.

Pedal clutch problem.

Novices do not control the clutch well, and it is easy to raise the clutch too quickly and the vehicle accidentally stalls when driving. Therefore, when starting with a manual transmission car, the clutch should be well controlled and the left foot should be steady. Although automatic transmission cars rarely stall, if the clutch is lifted too quickly, it will also stall.

2 4 brake problems.

Many novices drive manual transmission cars, and when braking, especially when braking suddenly, they often forget to step on the clutch at the same time, which will suffocate the car and turn off. So when braking, either take neutral or press the brakes and press the clutch at the same time. 3/4

The problem of lack of fuel in the car.

4 4 Lack of power problem.

If there is a serious lack of power while driving, it will also cause stalling.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find a timely solution, will provide you with a satisfactory answer! We hope you find this service helpful.

Cause the car is easy to stall are, one is that the throttle is too dirty and has too much carbon, and the throttle needs to be cleaned to relearn idling, and the other is that the oil is blocked by the dirty gasoline filter, in this case, the oil circuit needs to be cleaned to replace the gasoline filter, the gasoline filter is replaced every 40,000 kilometers, the spark plug is replaced every 60,000 kilometers, and the three-way catalytic converter is dismantled and washed, I wish you a happy car! Happy Year of the Tiger!

The reasons for the sudden shutdown of the car when the car is downhill in low gear can be divided into 3 kinds: the first one, some novice drivers have insufficient driving experience caused by driver misoperation, even on ordinary roads, it is possible to turn off because they have not mastered the clutch when they start, some people may know that when encountering a long downhill, if they have been relying on the brakes to slow down, a long time may cause the brake pads to overheat, and eventually lead to brake failure, so when going downhill, prepare to hang the gear into the low gear, and use the traction of the engine to limit the speed, However, because the clutch amplitude was not mastered, the car stalled.

If your car suddenly stalls when going downhill, you can try this orange to grasp the following method: for manual transmission cars, if there is a certain speed, keep the gear, slightly step on the Gaoqing throttle, and the car can drag the engine back on; If the speed of the car is very slow and you can't drag it, stop the car first, and then re-board the car according to the normal operation.
