It is difficult to start converse car.

Maybe the battery is out of order, the power storage is insufficient, and the starter

drive

If the engine speed is insufficient, it will be difficult to start.

If it's not a power shortage, it's the engine.

It is usually difficult to start the engine for the following reasons.

1. The throttle valve (idle valve) is dirty. Clean with cleaning agent (it will block the air from entering).

2, check the fuel pressure, whether the oil pump pressure relief, (can't store pressure, the car in the morning, the pressure is insufficient, it is difficult to open, the idle speed is unstable).

3. How much carbon is deposited on the air intake and the back of the valve (some fuel is absorbed, the mixed gas is diluted, and the combustion is not good).

It is suggested to focus on 1 and 2.

654.38+0.6 million kilometers, if the oil is changed on time and inferior gasoline is not used, the carbon deposit will not be much.

Even if you just do maintenance, you won't check all the parts of your car in detail. Now a lot of so-called maintenance is actually changing the oil. Check the oil lamp and water lamp, and the tire will be deflated.
