Bora in 04, sometimes step on the accelerator, and the speed can t go up why

1.The clutch slips, the reason for the automatic transmission is that there is less transmission oil, and the transmission oil must be replenished quickly, and the manual clutch is polished or stained with oil. Get it over as soon as possible.

2.The clutch pedal is too low and the clutch is not tightly combined, and then the clutch compression spring is loose or the compression force is unbalanced. 3.

It is recommended to go to the 4S shop to do an automatic transmission oil cleaning, and then let the 4S shop detect the car's engine sensor (the 4S shop has this kind of diagnostic equipment, which can obtain faults**) may be able to find out what the problem is. can solve the problem.

Visiting Wanggang is kneaded and crisp and dry.

It's normal and don't worry.

When stepping on the accelerator, it is not beneficial to bombard too high, 1, resulting in high noise, 2, large vibration, 3, high oil consumption, 4, for new hands and people who do not know much about the car, it is easy to misoperate and step on the accelerator deeply, and the speed is too high may also cause the vehicle to rush forward far when the clutch rental calendar is suddenly released, which is not conducive to safety, 5. The clutch is suddenly loosened at too high speed, which will also lead to excessive impact of the parts, wear and tear of the clutch, or the impact of the parts deformation or the fracture of the canton.

It could be because of the throttle.

Carbon deposits in parts such as idle motors.

Too much. It is recommended to check whether there is carbon deposition in the throttle valve, and then clean the carbon deposition in the engine intake and combustion chamber, which can be carried out by hanging the bottle, and finally use the diagnostic computer to detect whether the engine has a fault code, and initialize the fuel injection time of the throttle and fuel injector.

Reasons why you can't add the throttle:

1. Fuel system blockage, such as nozzles, gasoline filters, or fuel quality.

2. The air intake system is blocked, such as the air filter.

The air flow meter can not be fully burned with fuel oil.

3. The ignition system Huiyan works poorly, such as spark plugs.

High-voltage lines. 4. The gas distribution phase is wrong, such as the inlet and front dispersion exhaust valves are not tightly sealed.

5. It may be a problem with the oil, if you have recently refueled, and this problem is not before refueling, then there is a 70% chance that the oil at the gas station is a problem, and it may be mixed with water or other liquids.

6. It may be related to water ingress. If the engine enters the water through the air intake, there is a risk that the air pipe will bend, or the piston may be damaged, resulting in insufficient cylinder pressure, so that the car cannot refuel when stepping on the accelerator.

7. Long-term maintenance has not been done, resulting in the aging of various systems, so that the car can not be refueled when stepping on the accelerator.

The reason why Bora sometimes can't refuel may be because there is a problem with the ignition system or the oil supply system. 1.There was a problem with the ignition system.

The ignition system of the car includes a spark plug and an ignition coil of the mu mold. If there is a problem with the ignition system, the car will have a hydrogliding phenomenon that slowly rises when the accelerator speed rises. 2.

There is a problem with the air intake system. If the throttle valve is faulty or the intake manifold is leaking, the car's revs will not rise after the throttle is pressed.

The cause of this failure phenomenon may be a problem with the ignition system or the oil supply system.

Causes of failure:

1.There was a problem with the ignition system. The ignition system of a car consists of a spark plug and an ignition coil. If there is a problem with the ignition system, the car will slow to rise when the accelerator speed is pressed.

2.There is a problem with the air intake system. If the throttle valve is faulty or the intake manifold is leaking, the car's revs will not rise after the throttle is pressed.

3.There is a problem with the rapid burial of the oil supply system.

When the engine is working properly, the oil pump needs to establish pressure. If the pump is unable to build up enough pressure, the injector will not be able to dispense enough oil. The car will also be sluggish after pressing the accelerator.

4.The oxygen sensor is damaged.

The oxygen sensor is responsible for detecting the oxygen content in the exhaust, so that the ECU can adjust the air-fuel ratio according to the data of the oxygen sensor, and adjust various data such as the ignition advance angle. If the oxygen sensor is damaged, it will cause the car to fail to increase its speed after pressing the accelerator.

After the oxygen sensor is used for a long time, there will be carbon deposits and even lead poisoning, which will cause the oxygen sensor to malfunction. Many old cars will have the problem of rising fuel consumption and decreasing power, which may be related to the failure of the oxygen sensor. So, about normal driving suddenly can't refuel?

Summary. Dear, I'm glad to answer for you, the reason why the Bora automatic transmission throttle is still in the fourth gear position at 4000 rpm may be a problem with the accelerator pedal, it may be a problem with the spring of the accelerator pedal, or it may be a problem with the controller of the accelerator pedal. Or the engine output is insufficient:

It is possible that the engine is aging or damaged, resulting in a decrease in power output and the inability to drive the vehicle into gears.

Dear, I'm glad to answer for you, the original reason for the Bora automatic transmission throttle to step on the accelerator to 4000 rpm and still in the fourth gear position may be a problem with the accelerator pedal, it may be a problem with the spring of the accelerator pedal, or it may be a problem with the controller of the accelerator pedal. Or insufficient engine output: It may be due to the aging or damage of the engine, resulting in a decrease in output power and inability to drive the vehicle to shift.

Dear, I'm glad to answer for you, and it is also possible that due to transmission failure, the automatic transmission cannot change normally and stays in the original gear.

Generally speaking, the automatic transmission has the following reasons for the occurrence of "high throttle speed and slow speed": 1. The torque converter does not lock the torque converter, you can understand it as a pair of fans, one is connected to the engine, and the other is connected to the gearbox to rotate, so that the power of the engine is transmitted to the gearbox. The advantage of this structure is that it can be semi-synchronized at will like a manual transmission, and there is no need to worry about burning out the clutch.

Therefore, the automatic transmission car can stop when the brakes are stepped on, and the car can be left when the brakes are released. Hope mine can help you, and, thank you!

Summary. Hello, happy to answer your questions.

Hello, happy to answer your questions.

Hello, this has to read the fault code sent by the engine system and the like, for example, after the external temperature sensor has a problem, it will lead to the inability to add oil, or the accelerator pedal, the signal of the throttle is wrong, it will also lead to the failure to add oil, so it depends on the actual failure.

It was the same last time, I went to the repair shop to check it with a diagnostic instrument, and I didn't find a fault code, and then I refreshed and scanned it, and this time I couldn't add oil.

There will definitely be a fault record, but it is said that it has not been dealt with, and the fault has been eliminated directly, the most common is the external temperature sensor.

Where is the outside temperature sensor located.

Under the bumper in front, in the middle of the net, the fog light on the left is next to each other.

Well. If you feel that it is helpful to you, please give a 5-star like after the problem is over, and the platform will send you a coupon that can be used in cash next time.

One is to check whether the intake pipe is leaking. The second is to check whether the ignition time is too late. The third is to call up the fault code and analyze the cause of the failure.

Fourth, check the fuel injection system, such as fuel pressure and injector work. Fifth, check whether the ignition system, especially the shock sensor and igniter, are working properly.

1. The engine oil circuit system is the place where the car often has problems, the fuel injector is blocked, the oil pipe is leaking, the power of the gasoline pump is reduced, and the gasoline filter is blocked. The main reason why the car has a sense of powerlessness is that the engine does not have enough oil when going uphill, the combustion efficiency decreases, and the horsepower does not meet the requirements.

2. In addition, the same is true for the air intake system, in addition to the engine needs oil, it also needs air, if the air filter, throttle and other components are blocked or there are problems, resulting in insufficient air intake, it will also cause the car to accelerate weakly and slowly.

3. The spark plug is also the source of common faults, if the spark plug ignition is poor, it may lead to the problem of weak acceleration.

4. If the car is sluggish, and the car will feel the steering wheel or body shake significantly when it stops, then it means that at least one cylinder of the car's engine is running abnormally or stalling. In general, a four-cylinder engine can still run if one of the cylinders does not start, and as the number of cylinders increases, this symptom becomes more difficult to detect.

5. If the air conditioner is turned on in the summer, then the small displacement models will feel that the acceleration is difficult, and the fuel consumption has increased significantly, this is because the air conditioner needs to drive the compressor when working, and the power required by the compressor is very large, and the engine has to carry such a large internal friction, so it is inevitable that the acceleration will be slow and the acceleration is weak.

6. In addition, it can be judged according to other symptoms that there is a problem, such as black smoke from the exhaust pipe, then there is a problem with the combustion chamber, ignition system, and valve; If there is blue smoke coming out of the exhaust pipe, then it is possible that the engine oil has run to the combustion chamber, that is, the engine oil is burning.

7. Finally, there is a situation, that is, the tire pressure is insufficient, which will also lead to the feeling of the car's weakness to speed up.

Indeed, there will be many reasons for the slow acceleration of the car, but what can be known is that they are concentrated in the ignition, air intake, oil circuit and other systems of the engine, so as long as the elimination and inspection are carried out one by one, then the car can be eliminated from boring and slow acceleration and fuel consumption.

The reasons why Bora cars can't add the throttle: 1. The vehicle has too much carbon; 2. The quality of the oil is not up to standard; 3. The intake or exhaust system is blocked; 4. Spark plug aging; 5. a lack of cylinder; 6. Insufficient tire pressure; 7. The vertical force of the engine dynamic return is insufficient; 8. Problems with the combustion chamber, ignition system and valve; 9. The gasoline filter is too dirty, the gasoline pump is damaged, and the three-way catalytic is blocked.

Volkswagen Bora can not get up when stepping on the accelerator in general, it is caused by the ignition and fuel supply system leakage spine failure, at this time, you can first disassemble and inspect the spark plug, check the combustion status and gasoline pump pressure, and repair it according to the fault problem.

Reasons why the Bora car can't get the throttle up:

1. Excessive carbon deposition in vehicles;

2. The quality of the oil is not up to standard;

3. The intake or exhaust system is blocked;

4. Spark plug aging;

5. a lack of cylinder; 6. Insufficient tire pressure;

7. Insufficient engine power;

8. Problems with the combustion chamber, ignition system and valve;

9. The gasoline filter is too dirty, the gasoline pump is damaged, and the three-way catalytic is blocked.

Most of them find that there is no acceleration after stepping on the accelerator, the first task is that we can detect the throttle, stepping on the throttle will drive the throttle, trigger the position sensor, and then adjust the unit then it will pattern the throttle position to adjust the opening of the throttle, and then calculate the corresponding signal voltage, in the calculation of the amount of fuel injection of the car, if the throttle position sensor fails at this time, it will not be able to complete the entire acceleration process, and it is natural that the field stove will feel that the speed does not rise after stepping on the accelerator, At this time, it is necessary for a professional to carry out the repair.
