Causes of car running out of power when accelerating

1. Low pressure (diesel and gasoline engines)

In order for the car engine to operate smoothly and provide enough power to the vehicle, it is necessary to have enough pressure in the cylinder during the fuel combustion process. If the pressure is low, the engine's power will be limited. As a result, the engine cannot operate normally.

2. Air filter problem (diesel and gasoline engines)

The engine's combustion chamber is responsible for combining fuel and air together to create the thrust needed to run the vehicle. Before the air enters the combustion chamber, it must pass through an air filter... However, the air filter will often accumulate more and more dust and dirt from the outside during the vehicle's circulation.

Once a part of the air filter is clogged with dirt, it will limit the amount of air entering the combustion chamber, causing the vehicle to not have the necessary power to move smoothly, causing a loss of power when accelerating.

3. Air flow sensor error (gasoline engine)

The main job of the mass air flow sensor is to measure the amount of air entering the engine and then report it to the powertrain control module, which in turn calculates the load being placed on the engine. If there is a problem with these sensors, the engine's performance will be affected.

4. Camshaft sensor failure.

The camshaft sensor is responsible for collecting information about the vehicle's camshaft speed and then sending it to the electronic control module. Based on the information obtained, the control module will regulate the operation of the fuel injection and combustion. However, if there is a problem with the camshaft sensor that prevents it from sending information to the control module, the engine's operation will be seriously affected and not as desired by the driver.

5. Oxygen sensor failure (diesel and gasoline engines)

The oxygen sensor measures the amount of gas escaping from the engine. The electronic sensor then uses this information to calculate the air-fuel ratio present in the vehicle's engine, regulate fuel injection and combustion, and control emissions.

If there is a problem with the oxygen sensors, they can cause the engine to have difficulty starting, and have a negative impact on the environment because the electronic module does not properly control the emission control operation.

6. Injector failure (diesel and gasoline engines)

Fuel injectors are one of the most important parts to ensure that your car engine can function properly. If the fuel injectors are damaged or malfunctioning, the engine will not be able to produce enough power to make the car go faster.

7. Fuel line problem or weakness

The fuel line is responsible for transporting fuel from the vehicle's tank to the vehicle's engine. For the vehicle to operate well and reach maximum capacity, the fuel line must ensure adequate fuel flow, withstand and have reasonable pressure.

If there is a problem with the fuel line, the vehicle's acceleration is not guaranteed.

8. Fuel filter blockage (diesel and gasoline engines)

The fuel filter is located between the injector and the fuel line. The job of the fuel filter is to filter out any contaminants that may be present in the fuel before it is burned in the engine. If your fuel filter is too dirty, damaged, or clogged, the engine will not receive enough clean fuel, leading to a lack of power when accelerating.

In the event of a torn fuel filter, allowing contaminants into the engine, your vehicle is likely to suffer more serious damage.

9. Clogged exhaust pipe (diesel and gasoline engines)

There are usually two filters in a car's exhaust pipe: a noise filter and an emission control filter. The job of an emission control device is to cut down on pollutants before they are released into the environment. If the exhaust pipe or any of its filters is clogged, it will also weaken the engine's ability to operate, causing the car to slow down even when you try to accelerate.
