The start is very slow after maintenance and the throttle is heavy

Is the fault light on? Has fuel consumption increased?

Listening to your description, it should be that there is a cylinder that is not working, and it may be a problem with the spark plug.

It's not easy to draw conclusions about the specifics, so let's go to the store and check it.

If it is true that it is not a psychological effect, and the symptoms are obvious, it should be problematic.

What kind of gasoline do you usually add? 95 or 97, I have repaired a lot of cars because the oil is not good, which causes the fuel injector to be blocked, resulting in mixing gas imbalance. I won't talk to you in detail, let's go to 4S to check it out.

Sutar ( Check price |.)Detailed explanation of the model) Slow start solution: increase the torque of the engine in the low-revving area. The most effective way is to install turbocharging and external computers; The easy way to do this is to adjust the ECU to increase the reduction ratio in the first gear or increase the total reduction ratio.

The low torque output of the engine can be simply understood as the output of large torque when the engine speed is low, first of all, let's understand the concept of cylinder bore and stroke, the cylinder bore is the diameter of the cylinder, the stroke is the stroke distance from the lower point to the upper point of the piston, and the proportion of the engine bore and stroke. Large bore short stroke and small bore long stroke have their own advantages and disadvantages.

Large bore short stroke: the advantage is that the number of movements is increased due to the short reciprocating distance of the piston), which will increase the power of the machine, that is, the maximum travel speed will be increased, but due to the short stroke, the energy of each squeeze is small, the natural torque will be weak, if you want to increase the torque, you must increase the speed.

With the same horsepower, torque and power, the car must have a fast start in terms of specific gravity, which is no longer in doubt. If you ask, which starts faster is more horsepower or lighter weight? This pretense is incomparable, and it only makes sense to compare it among similar models.

The grip of the tires also has an impact on the start of the car, and a suitable tire is a key factor in ensuring the acceleration effect, because the tire is the ultimate expression of the engine's power output. Ordinary tires are designed and produced taking into account many factors such as comprehensive road conditions and cost, which can only be said to be enough for urban transportation, but can not provide the greatest grip, so if you want to improve the starting performance, a good tire hall can not be ignored.

Summary. Extended information: The throttle becomes heavier after the water temperature is high, which may be due to the deterioration of the vehicle's performance due to the overheating of the vehicle's engine.

Typically, a vehicle's engine automatically activates protection mode after a human overheats to prevent further damage to the engine. During protected mode, the engine is throttled and its power output is reduced, resulting in a poor acceleration ability of the car. This situation may be related to your car's cooling system, where the coolant may need to be replaced or an exhaust check is required.

You can check if there are air bubbles in the coolant, if there are air bubbles, it is possible that there is a fault in this cooling system. At the same time, if the coolant level is too low, the water temperature will also rise, so you need to make sure that the coolant level is within the proper range. It is best that you can take your vehicle to a professional car service center for inspection and repair to ensure the proper operation of the vehicle.

Hello dear, glad to answer for you! The throttle becomes heavier after the water temperature is high, which is due to the overheating of the vehicle's engine, resulting in a decrease in the performance of the vehicle.

Extended information: The throttle becomes heavier after the water temperature is high, which may be due to the overheating of the vehicle's engine, which leads to a decrease in the vehicle's hail energy. Normally, the vehicle's starting track detector will automatically activate the protection mode after overheating to prevent further damage to the engine.

During protected mode, the engine is throttled and its power output is reduced, resulting in a poor acceleration ability of the car. In this case, the crash sail can be related to your car's cooling system, where the coolant may need to be replaced or an exhaust check is required. You can check if there are air bubbles in the coolant, if there are air bubbles, it is possible that there is a fault in this cooling system.

At the same time, if the coolant level is too low, the water temperature will also rise, so you need to make sure that the coolant level is within the proper range. It is best that you can take your vehicle to a professional car service center for inspection and repair to ensure the proper operation of the vehicle.

There are many reasons for this. It could be that there is a problem with the throttle, the oil viscosity is too high, or there is too much oil.

If the oil level falls below the minimum scale, the engine will be poorly lubricated. If the oil level is higher than the maximum scale, the internal resistance of the engine will increase when it is running, and the engine speed will rise slowly when the throttle is pressed.

2.There is a problem with the throttle: The throttle is called the throat that starts the reed machine. If there is a problem with this part, it can cause problems with the engine air intake.

3.Oil viscosity is too high: If the oil viscosity is too high, the internal resistance of the engine will be too large when running, resulting in the engine speed not being able to rise quickly after pressing the accelerator pedal.

4.Problems with the engine ignition system: If there is a problem with the spark plug and ignition coil, it can also cause the engine to not be able to accelerate slowly after pressing the throttle.

Spark plugs should be replaced every once in a while. If it is not replaced for a long time, the spark plug electrode gap will increase, and too much carbon will be deposited on the spark plug electrode.

When choosing the type of oil, it should be chosen according to the technical characteristics of the engine. Generally, naturally aspirated engines can use 20 or 30 oil, and turbocharged engines can use 40 oil.

Millions of car purchase subsidies.

Summary. Volkswagen Sutar has a cold start in the morning and the throttle is very heavy. It is due to the problem of the accelerator pedal itself, or the engine is caused by the protection due to low temperature, this situation is due to the new car, can not be repaired outside, you can drive the car to the 4S shop, after placing it overnight, wait for the second day of the cold car state let the master help you check it, there is a problem that the accelerator pedal itself becomes heavier, directly replace the original pedal on the line, the general fixed parts need 7 15 days cycle, at this time you can drive the car away, wait until the pieces are replaced later, or use the diagnostic instrument to upgrade the engine program, The engine is released from low temperature protection, and the power can also return to normal when the car is cold.

Only 3000 km.

Volkswagen Sutar has a cold start in the morning and the throttle is very heavy.

What's wrong with the accelerator pedal.

The quality of the pedal itself, when the ambient temperature is low, the accelerator will become heavier when the car is low, this situation is very common on the Volkswagen car, you go to the 4S shop to let the master help you confirm, it is indeed a bad situation, just replace the pedal directly.

Summary. Hello, in this case, there is time to clean the throttle first, and then the oil pump pressure and gasoline filter to see if it is too dirty, not good oiled, and the spark plug ignition coil to see if the fire is weak, caused by fire.

In 18 years, my car was a significant setback, especially when driving at low speeds, loosening the throttle and then stepping on the throttle.

Hello. Hello, in this case, there is time to clean the throttle first, and then the oil pump pressure and gasoline filter to see if it is too dirty, not good oiled, and the spark plug ignition coil to see if the fire is weak, caused by fire.

My car has been soaring for 18 years, and the current situation is that the shift is 2,000 turns slower before jumping, and when walking, there is a setback in oil production and oil collection, what is the cause of this?

Focus on checking the oil pump pressure, ignition coil, spark plug and gearbox valve body to see if there is any problem.

The oil pump, spark plug ignition coil are all checked.

If it's okay, you need to see if there is a problem with the gearbox valve body.

The state of the abrupt gap between oil production and oil recovery while driving.

Isn't the gearbox valve body a hassle?

Should the gearbox valve body be lifted down the gearbox?

If it is a valve body, it is necessary to disassemble the gearbox and check it.
