The Bora 1 9t engine is weak

Go check it out. Common causes of insufficient engine power;

1) Oil, faulty circuit. The oil circuit is not smooth, the air intake is blocked, and the gas is mixed and the gas is too thin or too thick; The ignition time is too late or the contact gap is too small or too large; engine exhaust pipe leakage; Leakage or detachment of high-voltage distribution lines, leakage or channeling of distributor jacks; The distributor cam is worn unevenly or the spark plug has too much carbon deposit, and the crack leakage.

2) Insufficient cylinder pressure; The cylinder gasket is not sealed, ablative; Valve seat inserts are ablative, unsealed or detached; The valve springs are too soft and work poorly; piston rings bite or match; The piston clearance between the cylinders is too large.

3) Gas distribution phase abnormality;

4) A few cylinders do not work.

5) The engine temperature is too high; The water pump, thermostat is not working well, the belt is slipping, the cooling system is too limescale.

6) The chassis is faulty. The clutch slips, the brakes bite, and the tire pressure is low.

According to your situation, you can make a preliminary judgment method as follows: disconnect the fuel injector plug one by one, when disconnecting a cylinder, the jitter has no obvious change, you can preliminarily determine that the cylinder is not working well, and further check the ignition coil and spark plug. If there are no accessories in hand, the interchange method can be used to swap the accessories of other cylinders and then observe whether there is any change in the working of the cylinder of the engine, and determine the fault point.

If it is not for the above reasons, you can consider whether the sensor signal is biased, whether the idle motor is stuck due to carbon deposits, and whether the speed sensor is working normally. If you use a Volkswagen tester for testing, you will have a satisfactory answer.

Good classic diesel supercharged engine, this car mainly relies on turbo acceleration, and turbo heat dissipation is very important, there are many problems of powerlessness, cylinder pressure, spark plugs, domestic diesel is even dirty, is it filtered and blocked, and there is a high-pressure pipe leakage, I have encountered this problem before.

Friend's displacement should be written wrong, but there are many reasons for insufficient power, such as incomplete combustion, excessive carbon deposit, oil quality problems, gearbox failure, ==== It is recommended that friends can go to the 4S shop for maintenance and troubleshooting.

Hello in this case it is recommended that you replace the spark plug and clean the fuel injector.

Hello, the quality of the oil is not good, or there is too much carbon.

1. Caused by carbon deposits.

There are three causes of a car's inability to accelerate, the first is the valves, the idle motor, the intake tract and the inside of the combustion chamber, and the spark plugs.

and other parts of the carbon deposit, so when the car idles, there will be a fire incident.

2. Driving on congested roads.

The car drives for a long time on a congested road, accelerating and slowing down, so it will eventually cause the car to show a feeling of weakness when driving again.

Third, the quality of oil is poor.

One of the most important reasons for the acceleration weakness of the car is also the problem that many car owners have with the acceleration weakness of the car is that the quality of the oil used is poor, which will affect the gasoline filter element and the oil circuit, which may lead to poor oil supply, resulting in weak acceleration; It will also affect the three-way catalytic converter of the exhaust system.

If the three-way catalytic converter is blocked, it will also directly affect the acceleration of the vehicle, and will also lead to an increase in fuel consumption, resulting in weak acceleration.

Reasons for Bora's weak start: 1. There is a problem with the engine or gearbox; 2. The vehicle displacement is small and heavy-loaded; 3. The valve seal is not tight, and the cylinder pressure is insufficient; 4. Excessive carbon deposition in the inlet tract; 5. The spark plug has carbon deposition or wrong gap; 6. The fuel injector is blocked, and the fuel injection volume is insufficient.

Check the state of the battery, and the difficulty in starting the car in winter is mostly caused by the loss of battery power or the expiration of the battery's service life. When the battery is low, the speed is weak when starting the car, and only the clicking sound is heard, and the clicking sound will gradually become a clicking sound when the ignition is lit again. Do not ignite continuously to avoid the battery running out.

2. Change the appropriate engine oil in winter, as the temperature decreases, the viscosity of the engine oil will increase, and the oil flow will be difficult, so that the engine resistance will increase. If it is difficult to start, check whether the oil label is incorrect.

3. Timely replacement of spark plugs After a few years of use, spark plugs are easy to cause problems such as carbon deposition, leakage, excessive gap, and ablation, which will cause difficulties in car ignition, cold start, and even heat engine start, and often need to be ignited multiple times. Therefore, when driving to a certain number of kilometers or feeling that the vehicle is difficult to start, driving weakly, shaking, increasing fuel consumption, or inexplicably stalling, please check the status of the spark and replace it in time.

The causes and solutions are as follows:

It is generally caused by insufficient combustion of the engine, it is recommended to go to the repair shop to replace the spark plugs, clean the injectors, and check whether the gasoline pressure is normal.

Poor quality oil used will affect the gasoline filter and oil circuit, which may lead to poor oil supply, resulting in weak acceleration and replacement of good quality oil.

Carbon deposits occur in the valves, idle motors, air intakes, combustion chambers and spark plugs, so when the car is idling, there will be a fire incident to clean up the carbon deposits.

A car is a car that is used to transport people and their belongings, and the seats are arranged between two axles. The maximum number of seats, including the driver, is nine. In general, sedans emphasize comfort and focus on the occupants.

Moreover, starting from economic considerations, choose an engine with moderate horsepower, small displacement, and low fuel consumption.

Summary. Hello, your failure is caused by insufficient power, and there are reasons.

Ignition system working poorly:

The fuel injection system is faulty:

The three-way catalytic is clogged!

The 2004 Bora hand self-integrated uphill has no power for any reason.

Hello, the failure of your Nadoudan is caused by insufficient power, and the reasons areIgnition system working poorly:The fuel injection system is faulty:The three-way catalytic plugging pants are plugged with holes!

First check whether the ignition energy of the ignition system, ignition coil, and spark plug is normal! Then check whether the fuel injection system, the pressure of the gasoline pump is normal, whether the fuel injector is blocked, the air intake sensor, and whether the signal of the fuel injection correction sensor is normal! If it is normal, it may be that the three-way catalytic is blocked, and the exhaust eggplant is not good to tremble brother buried, I am very happy for your question.

I hope I can help you with my balance, and I hope you can give me a thumbs up, your evaluation is very important to me, thank you, I wish you a happy life, a lot of money, and good luck. 

Special fuel fee. Special fuel fee.

Burn engine oil severely.

It is appropriate to choose to add a viscous oil to the engine to increase the sealing of the engine fiber and plug and cylinder wall. Of course, the final solution to the problem of burning engine oil is to overhaul the vehicle more thoroughly, so as to solve the problem from the root.

5w—40 um. That's fine.

Change the oil-gas separator, and finally open the cylinder to change the piston ring to see if the cylinder barrel is worn.

Is it a good deal for such an old car.

Changing piston rings is a small job, and it will not exceed 3000

Whether it's cost-effective or not, you can see how long it will take to drive.

Now the car in D gear will not move, and it will not go until you step on the accelerator.

2.It may be related to the problem of the gearbox itself controlling the vertical system and the signal of the actuator asking the imaginary ruler, and the shift valve is not sensitive, resulting in the shift is not in place, and the oil channel can not be opened.

What's the problem.

It may be that the engine's throttle is too small and the injector does not inject enough fuel.

If the added fuel is of poor quality, when there are too many impurities or water in the fuel, it will lead to insufficient power, and inferior fuel is very easy to cause gasoline filter, oil pump filter and fuel injector, which have small holes or filter parts to cause blockage, resulting in poor oil supply and reduced engine function.

If the quality of the fuel is poor, when there are too many impurities or water in the fuel, it will lead to insufficient power, and the inferior fuel is very easy to cause the gasoline filter, oil pump filter screen and fuel injector with small holes or filter parts to cause blockage, resulting in poor oil supply and reduced engine function. For car-related expenses, the fuel cost is relatively frequent, and it is understandable that many car owners choose to refuel at relatively cheap gas stations. Now many gas stations, including PetroChina, Sinopec will also regularly launch some discounts, we choose the best in line with our expectations of the gas station when the disturbance, but also need to pay more attention to the relevant reputation, try to choose a more well-known chain or business better, good reputation of the station.

The Bora is FAW-Volkswagen's first self-designed model, and is known as a new car that "inherits the classics and surpasses the classics".

Bora: In 2001, the Volkswagen Group's all-new sedan officially debuted in China under the name "Bora", and has established a good reputation as a "driver's car" with its dynamic styling and leading technology.
