17 corolla 1.2t What's your frustration?

Pacific Auto Network 1, the oil circuit is blocked, and the oil circuit, nozzle, oil circuit and oil pipe are cleaned; 2. It is normal for automatic transmission auto start to have setbacks; 3, automatic start-stop plus dual clutch gearbox, itself has this problem 4, ignition is not normal, replace the spark plug or high voltage package.

First of all, the frustration of the car is mainly caused by the engine and clutch. In this case, the car's failure to accelerate is definitely related to the engine, and the ignition, air intake and fuel nozzle determine the combustion of fuel, which is also the power source of the engine. Then the lack of acceleration is naturally related to the ignition, air intake and fuel injection systems.

If the car has a sense of frustration when accelerating, the owner can first make a simple inspection of the vehicle, such as checking the fuel quantity, whether the engine throttle, nozzle, spark plug and three-way catalytic converter have not been maintained for a long time. Usually these parts will produce carbon deposits for a long time, which will affect the power of the car.

Stagnation can be divided into sporadic and fixed periods. The difference is simple. Accidental means irregular, fixed means reaching a certain speed or changing a certain gear (second gear into third gear) and a fixed speed appears.

The reason is that there is sludge in the gearbox oil, and the oil passage in the valve body will be blocked in the gearbox, which will lead to a series of gearbox problems such as high temperature, impact and slippage for a long time. Of course, there are other things that may lead to this situation:

1, the oil circuit is blocked, so clean the oil circuit, nozzle, oil circuit and oil pipe;

2. It is normal for automatic transmission auto start to have setbacks;

3, automatic start-stop plus dual-clutch gearbox, itself has this problem.

4. If the ignition is abnormal, replace the spark plug or high-voltage bag.
