What is the problem of weak acceleration when the car is driving?

1. It may be caused by carbon deposition in throttle, idle motor, intake and combustion chamber, and spark plug.

2. It may be that driving in a congested road section for a long time will also lead to weak acceleration;

3. The poor quality of the engine oil that may be used will affect the gasoline filter element and oil circuit, resulting in poor oil supply, which will lead to weak acceleration; It will also affect the service life of the three-way catalyst in the exhaust system. If the three-way catalyst is blocked, it will directly affect vehicle acceleration and increase fuel consumption.

4. It may be that the sensor is faulty, which leads to the phenomenon of weak acceleration.

It is recommended to check the transmission oil first. If the oil is brown and smells of burning, then the clutch plate of the automatic transmission is burnt out, which leads to slipping when accelerating, so the car stops and returns to normal after the situation occurs.

In this case, it is best to go to the repair shop as soon as possible to replace the new clutch plate and gearbox oil to avoid the deterioration of the situation.
