What is the reason for the slow acceleration of the car?

The slow acceleration of the car may be related to the fuel oil or the engine.

It may be caused by the owner adding inferior gasoline or mislabeled gasoline. Inferior gasoline will not only damage the engine, but also reduce power and increase fuel consumption, so there will be a phenomenon of slow speed increase and no power. When the clutch fails, the clutch slips during driving, and the power of the engine cannot be completely transmitted to the driving wheels. Even if the owner accelerates the engine, it will not speed up because of the clutch, and the speed increase is slow and weak.

It may also be caused by an engine fault, such as a problem with the oil system of the engine. At this time, we should check whether there is insufficient lubrication caused by lack of oil. Problems in the air intake system and ignition system can also cause this situation, mainly to check whether the air filter and throttle are blocked and whether the spark plug is atomized.

The solution of automobile acceleration weakness

1. Replace the engine intake pipe.

2. Adjust the ignition time.

3. Replace the fuel injection system.

4. Replace the throttle position sensor.

5. Check the three-way catalytic converter.

6. Replace high-grade fuel.
