The cheetah CS 10 I bought ran 14500 km, so it's not easy to start now. I went to the 4S shop several times and said that the normal fuel consumption was 16 to 18, so I asked for help.

Common causes of engine starting difficulties:

1. Ignition difficulty caused by car carbon deposit, accompanied by slight jitter when idling. Cleaning the throttle, cleaning the carbon deposit at the air inlet and cleaning the fuel injector can solve the problem.

2. The ignition energy of the spark plug is very weak. In order to save money, some car owners do not replace the spark plug after the maintenance cycle, which will cause the spark plug to turn off when the ignition energy drops seriously. Moreover, at present, the engines of many models are mostly in-cylinder direct injection, so the requirements for spark plugs are higher.

The first reason is battery damage. If this is the reason, it is difficult for ordinary car owners to find out for themselves, and they all need to be sent to a repair shop for testing through professional computer equipment. In addition, it is also possible that the battery is dead. If you often drive at a low speed in the city, the headlights, air conditioners, stereos and other equipment are always on, the battery consumption will be relatively large, and there may be a shortage of electricity. I suggest you run at high speed to fully charge the battery.

The second reason is that the mixing ratio of cars is abnormal, which is also the most common and typical reason. In this case, the engine is usually normal, but it just won't start. This phenomenon usually occurs because the throttle valve, intake valve or idle motor are too dirty. If the valve is too dirty, the oil will spray to the back and be absorbed by the carbon deposit, so you can't touch the car. General cleaning can solve the problem.
