The Bora car suddenly lacks power, restarts normally, and there is no fault code?

Reasons for lack of power.

1. Due to the blockage of the vent of the fuel tank cover, the fuel tank switch, the fuel filter and the oil pipe between the fuel tank and the carburetor are partially blocked, which cannot meet the required oil volume, resulting in the mixture being too thin and the engine working weak. Due to the long-term use of the air filter is not cleaned in time, the blockage, the lack of air volume will cause the combustible mixture to be too thick, so that the engine power will be reduced. The use of low-octane gasoline, the use of gasoline for too long, due to volatile deterioration resulting in too low octane number, easy to cause detonation, so that the engine power decreases.

Carbon accumulation in spark plugs and other parts increases fuel consumption. There is water and air in the oil circuit, which will affect the smooth flow of fuel. The muffler has too much carbon, which increases the exhaust resistance.

2. The ignition timing is inaccurate and the ignition is too early, which causes premature ignition and detonation of the combustible mixture. Due to the failure of the ignition system, the spark plug is broken or the spark plug spark is weak.

3. Compression pressure of the cylinder: the piston, piston ring, and cylinder are seriously worn, resulting in an increase in the matching gap between the piston, the piston ring and the cylinder, and the poor sealing, resulting in the leakage of the cylinder head and reducing the compression pressure of the cylinder. Due to the poor sealing, the crankcase leaks, which reduces the suction power.

Resolution. 1. Check whether the air filter is blocked, and remove it if necessary.

2. Check the throttle opening. When the accelerator pedal is pressed all the way down, the throttle should be wide open. Otherwise, its cable should be adjusted or the pedal position sensor and throttle position sensor should be learned.

3. Check whether the high-voltage line, spark plug and high-voltage spark are too weak.

4. Measure whether the fuel pressure is too low, and check the electric fuel pump, oil pressure regulator and gasoline filter if necessary.

1. If you run out of gas, try it with a different brand of gasoline.

2. Change the oil and filter.

4. Try the car to do a carbon deposit cleaning job.

5. Think about whether you have been wading in the water recently and go to the repair shop for further inspection.

This requires a test run of the vehicle and a detailed inspection, and it is recommended to go to a professional maintenance company for inspection.

The reasons why the Bora car suddenly started like a world annihilation could not move: 1. The power of the car battery is insufficient, and it cannot be successfully ignited when it starts; 2. The starting motor of the starter is faulty and cannot ignite; 3. There is a fault in the ignition system or fuel injection system of the vehicle, resulting in the spark plug not igniting or the fuel injector not injecting fuel; 4. When the owner starts the slag limb fire, the car gear is hung up incorrectly, and the automatic transmission vehicle can only be started when it is hung in the P gear.

The car won't catch fire for the following reasons:

1. The power of the car battery is insufficient, and it cannot be successfully ignited when starting;

2. The starting motor of the starter is faulty and cannot ignite;

3. There is a fault in the ignition system or fuel injection system of the vehicle, resulting in the spark change plug not igniting or the fuel injector nozzle not injecting;

4. When the owner starts the ignition, the car gear is hung up incorrectly, and the automatic transmission vehicle can only be started when it is hung in the P gear. The car won't catch fire

1. The battery can be fully charged, or the battery service life has expired, then the owner should replace the battery;

2. Convert the computer into mechanical energy through the starter to start the car.

1. Cause of failure: The gear is hung in P gear, and some models cannot be ignited if the gear is not in P gear. Solution: Hang the gear back to P.

2. Cause of failure: battery power loss. When the car battery loses power, the car will not be able to hit the car, and there are many reasons for the loss of car battery, such as the lack of water in the battery, or the battery is faulty, and the use of air conditioning for too long will cause the car battery to lose power.

Solution: Go to a specialized repair shop for maintenance.

There are two scenarios when the engine fault light is on:

1. The yellow symbol light indicates that the engine is faulty, but the fault does not affect the normal operation of the engine, but it must be tested and repaired.

2. The red symbol light indicates that the engine has a serious fault, and it needs to be repaired immediately under normal circumstances, if it is in special road conditions, it can be used in an emergency, but it is necessary to pay attention to the working status of the engine at all times. If the water temperature is too high or the oil pressure warning light is on, if you obviously feel that the vehicle is faulty, you should immediately pull over and call the maintenance station to request rescue to avoid affecting the performance of the engine.

The reason why the Bora engine failure light is on:

1. If the combustion state of the engine is not good, the fault light will be on. In order to ensure that the engine of the car is in good working condition and maintain the normal service life, an oxygen sensor is installed to detect the combustion state of the engine during the design. If the combustion condition of the engine is not good, it will increase fuel consumption and wear, and it will also pollute the environment.

2. Poor fuel quality. Automobile engines have certain requirements for the quality of fuel, and now the requirements for fuel quality are getting higher and higher. If the quality of the oil you add is not good, of course the engine failure light will come on.

3. There is carbon deposit in the engine cylinder. As the operating time increases, a certain amount of carbon deposits will form inside the engine. These deposits can cause changes in the engine's design parameters.

4. When the thermostat is abnormal, the engine fault light will also be on. If you see that the water temperature gauge does not rise to the ideal temperature (usually 90 degrees) for a long time in the car, the engine fault light will turn on.

Engine misfire.

If the spark plug ages, it can cause the engine to catch fire, and the engine fault light will come on. Remove the spark plug and observe if the electrode void is too large and if there is any black particulate material around it. If this is the case, it can be confirmed that the spark plug is aging and that the engine is catching fire.

Solution 3: Replace the spark plug, the cost of 4S shop is about 150-200 yuan, and the cost of repair shop is about 100-250 yuan. Spark plugs are wearing parts and are not covered by warranty, and it is recommended to replace them after 20,000 kilometers.

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.
