Sagitar, step on the gas pedal, no acceleration, no weakness.

Maybe the throttle is broken, some sensors are broken, the oil is added too much, or the oil viscosity is too high.

The throttle is called the throat of the engine. After we step on the accelerator pedal, we control the throttle opening instead of directly controlling the fuel injection.

When the accelerator pedal is depressed, the throttle opening becomes larger, so that the air entering the engine will increase, and ecu will command the fuel injection system to inject more fuel.

If the throttle is damaged, the engine speed will not rise and the car will not accelerate after stepping on the throttle.

There are many sensors around the car engine. If some sensors are damaged, the engine will not work properly.

There is oil in an automobile engine, which is called the blood of the engine. Engine oil plays the role of lubrication, cleaning, sealing, heat dissipation, buffering and rust prevention in the engine.

The viscosity of oil should not be too high or too low. When the viscosity is too high, the internal resistance increases when the engine is running, which leads to the decrease of engine power and the increase of fuel consumption.

If you add too much oil, the running resistance of the engine will increase, which will also cause the engine power to decrease.

When adding engine oil, the oil level should not be lower than the lowest scale on the dipstick or higher than the highest scale.

If the oil is increased too much, the three-way catalyst may be damaged.
