What is the reason why Volkswagen LaVida100000 km can't afford to speed up?

Hello! This situation needs to check the following aspects.

1. The engine is unstable because the throttle is too dirty, so cleaning the throttle can solve it.

2. The ignition ability of the spark plug is not good, resulting in incomplete combustion of the mixed gas, so it is generally replaced.

3. The oil supply of gasoline pump is not smooth, and the atomization effect of nozzle is not good. Need to check and test.

4. Three-way catalytic blockage leads to poor exhaust and stuffy refueling. Need to soak or change the potion.

5. Mechanical failures such as inaccurate timing and insufficient cylinder pressure will lead to automobile acceleration. It is recommended to go to the maintenance station to read the fault code and lock the target for inspection. If there is something wrong with your car, I hope my answer can help you.
