What are the problems in starting the cold car in summer?

The cold car needs high ignition energy when it starts, and the electrode gap of the spark plug will become larger after a certain mileage. If the electrode gap exceeds the standard, replace the spark plug in time.

2. Clean the throttle valve

The carbon deposit on the throat wall of the intake manifold will affect the intake air volume, and the carbon deposit behind the valve will adsorb fuel and affect the gasoline atomization. If there is carbon deposit, clean the air inlet.

3, check the gasoline pressure

The gasoline pump has low pressure and insufficient oil supply, which makes it difficult to start. In this case, replace the gasoline pump or switch several times to increase the pressure of the gasoline pipe and make it easy to start.
