After my car was repaired, the speed was too slow, is there still a problem?

No need to change. Oh, usually go to a more regular gas station to refuel, good fuel is basically no impurities, no damage to the engine and fuel supply system. If you feel that the car has been driving for a long time and the car is not as impulsive as before, it is recommended that you go to a 4S shop to do an oil circuit cleaning (including cleaning the fuel pump, throttle valve, spark plug, fuel injector, intake and exhaust valves, etc.).

It doesn't cost you much money, just more than two or three hundred all-inclusive. After this cleaning, it ensures that your car runs better than before, which makes it much more fuel-efficient! After the car runs for a long time, the oil circuit in the nose will be more or less dirty.

And usually pay more attention to the maintenance of the car, can drive but will not maintain the car, it will always be only Lainiao Hehe I wish you.

Hello in this case, it is recommended to clean the throttle and carbon injector first. Try replacing the spark plugs.

Hello, this situation mainly depends on what you have repaired before, check if the spark plug and throttle are too dirty.

This depends on the degree of engine maintenance of the landlord. If the engine is overhauled, after the repair, the performance and power will be somewhat different from the original factory. That's for sure.

Hello. This needs to be based on what aspect you are repairing. If you haven't cleaned up the carbon deposits from your engine. Personally, I recommend that you do a 3 cleaning to clean up the carbon deposits.

If the car has been repaired, it may need to be run in for a while, and the lack of power may be due to the fact that the engine cylinders are not working particularly smoothly.

It depends on what is the situation before the maintenance and what is the situation after the maintenance? Is the slow acceleration a problem of the oil circuit or the circuit, a mechanical problem or a comprehensive problem?

Hello, what fault is specifically repaired.

Some people, when they are driving, usually have the problem of slow car speed, and at this time they will wonder if their car is broken. I will also wonder if it is because of the engine power, which leads to such a phenomenon. Then we can see that if your car accelerates very slowly, it will also cause you to be irritable while driving.

And for such a problem, it will also affect the mood of driving. In fact, we can see that some professionals have given us some answers to questions, that is, if the speed is very slow in the process of driving, it is caused by the lack of oil in the engine. <>

Because the car is running low on oil.

At this time, we need to replenish enough oil to the engine to eliminate some of these problems. And for the unimportant step of refueling the car, we are also able to open some doors on the passenger side, pull the switch on some hoods on the left side of the driver's leg, and then add some of our own gasoline to the surface of the liquid cavity. It can ensure that some of these engine oils are very sufficient, and there will be no problem of slow car speed.

For automobiles, it is also a kind of machine. <>

Some oil needs to be replenished.

Therefore, when the engine oil is insufficient, it will produce a state where the speed is very slow and even can no longer work. We need to pay attention to such a state, if we don't care about it at all, it is likely to cause some damage to the car's local life. At this time, it is also a relatively large loss for our own cars.

There are even some of them who don't look for any reason when the car is slow, and they attribute such a responsibility to the brand of the car. Then we will also find that there are some car brands that are also very good, and they are also very high in the world. Then we blindly shift the responsibility to the brand side of the car, which is also very irresponsible.

Yes. When there is a problem with the engine, the speed of the car's hand gear becomes slow. Yu Shu shouted that at this time, he must go to the field for maintenance, and he must regularly clean up the carbon deposits in the engine, so that the engine can be used better.

It should be the grinding of the eyes, if there is no problem with the start of the Huai Cong machine, the speed is still relatively fast, and the speed is not particularly slow, you can check it, so that you can lead the cherry blossoms to know if it is a problem with the engine.

Not necessarily, depending on how slowly the car accelerates, but also pay attention to check for engine failures, or it is possible that there is a problem with other systems.

It is possible, it is also very possible that it is caused by the lack of oil, and it is also very possible to go for an examination.

The car is slow to speed up, not because of the engine. It may be caused by a lack of oil in the engine.

It is very likely to be related to the valve in the engine, or the phase of the gas distribution, etc., after these failures, the direct impact is that the cylinder compression ratio in our engine is too low, and the explosive power of gasoline combustion is not enough.

1. Tires. If the tire pressure of the tire is too low, the friction between the tire and the ground will increase, and the drag will increase after the friction increases, and the fuel consumption will increase after the resistance increases. If you find that the driving distance of the car decreases during driving, you have to check whether the air pressure of the tires meets the standard.

2. Ignition system.

The spark plug generally has to be replaced every 40,000 kilometers, such as the hole wheel fruit car has been driving for 3-4 years, then the spark plug must be replaced. If the spark plug is not replaced, the efficiency of the ignition system will be reduced, the speed cannot be increased, and the fuel consumption will be increased.

3. Carbon deposits. Carbon deposition is unavoidable, only frequent cleaning can be done, if the carbon deposition is too much, the exhaust valve, piston top, spark plug, cylinder edge, etc. will be greatly affected, in driving, want the car to have more power, you can only step on the accelerator, so that the speed will definitely increase, acceleration powerless, fuel consumption is getting higher and higher.

Fourth, oxygen sensor.

The oxygen sensor is located on the exhaust pipe and is a ceramic element that detects and controls the ratio of oxygen to fuel. After a long period of use, the electric fuel injection system will not be able to obtain information about the oxygen concentration in the exhaust pipe, and the mixture concentration in the engine will become higher, and the fuel consumption will naturally increase.

5. Air intake system.

This is mainly the air filter for engine intake and intake. In some of the more polluted areas in China, the air filter should be replaced regularly, otherwise it will lead to too much dust in the air filter, which will make the air intake smaller, the engine is difficult to burn, the speed can not be increased, and the fuel consumption will increase.

This can be related to the valves or valve timing in the engine. After these failures occur, the direct effect is that the cylinder compression ratio of our engine is too low, and the explosive power of gasoline combustion is not enough.

1. Tires. If the tire pressure is too low, the friction between the tire and the ground will increase the residual force of the stove, and the resistance will increase after the friction increases, and the fuel consumption will also increase after the resistance increases. When you find that the car is sliding less distance while driving, you have to check if the air pressure of the tires is up to standard.

2. Ignition system.

Generally, the spark plug needs to be replaced every 40,000 kilometers. If the car has been in operation for 3-4 years, it must be replaced. If the spark plugs are not replaced, the efficiency of the ignition system will decrease, the speed will not increase, and fuel consumption will increase.

Three. Carbon deposition.

Carbon deposits are inevitable and should only be cleaned frequently. If there is too much carbon deposit, exhaust valves, piston tops, spark plugs, cylinder edges, etc. will be greatly affected.

When driving, if you want the car to have more power, you can only step on the accelerator, so that the speed will definitely increase, and the fuel consumption will become higher and higher.

Four. Oxygen sensor.

The oxygen sensor, located on the exhaust pipe, is a ceramic element whose function is to detect and control the oxygen-fuel ratio. After a long period of use, the computer of the electronic fuel injection system cannot obtain information about the oxygen concentration in the exhaust pipe, and the concentration of the mixture in the engine will increase, and the fuel consumption will naturally increase.

The verb (abbreviation of verb) is the air intake system.

This is mainly the engine intake and intake air filters. In some seriously polluted areas in China, the air air filter should be replaced regularly, otherwise it will lead to too much dust in the air air filter, thereby reducing the air intake, making the engine difficult to burn, unable to accelerate, and increasing fuel consumption.

Summary. Hello, I am helping you sort out the answers to your questions, please wait a while Oh What's the matter with the slow lifting speed after car maintenance.

Hello, I am helping you sort out the answers to your questions, please wait a while What is going on with the slow lifting speed after car maintenance What is going on with the slow lifting speed after car maintenance Is there a fault code and what is maintained.

After the first warranty, there is no fault, change the oil, air filter.

Is it obvious after that. The speed up is noticeably different from before.

You put the air filter and see if it's installed.

In the past, the oil was in place, but now the oil cannot be fastened.

Most of this is psychological.

A feeling that in fact, there is not much of a problem, have you asked a master to test the car.

It's all at low speeds. The speed of the oil is high, and the speed of the car is slow.

What kind of model, did you test it with the master?

Cadillac luxury type teaching.

Go to the store computer to check the engine data stream.

If I can help you, please give me a thumbs up Thank you!
