What is the reason why Chery Tiggo doesn't ignite (what is the reason why Chery Tiggo doesn't ignite)

Unstable idle speed is caused by dirty throttle or excessive carbon deposit in injector, ignition system problems and unstable oil pressure. The throttle is too dirty or the injector has too much carbon deposit. When there is too much carbon deposit in the engine, the gasoline sprayed by the fuel injection head will be absorbed by a large amount of carbon deposit during cold start, which leads to too thin mixture during cold start and difficult start. In this case, it is easy to start the car only if the gasoline with carbon deposits is saturated. After the car starts, the gasoline adsorbed on the carbon deposit will be sucked into the cylinder by the vacuum suction of the engine for combustion, which will make the mixture thicker and the combustible mixture of the engine thinner and thicker, leading to cold start. Clean up the carbon deposit on the throttle or injector in time. Ignition system problem. Check the working conditions of spark plugs, high-voltage lines and ignition coils. Poor ignition system and poor ignition of spark plugs can also lead to such failures. The solution is to check whether there is too much carbon in the spark plug and replace the spark plug. The oil pressure is unstable. For example, the engine carbon deposit has been removed, the throttle valve has been cleaned, and the oil pad and spark plug have been replaced. It is still found that the body is unstable when idling. I suggest you go to the 4S shop to check whether the oil supply pressure and intake pressure sensors are normal. If the oil supply pressure of the oil pump is abnormal or the intake pressure sensor is wrong and not working well, it will cause the body to shake. The solution is to check the oil pressure and replace the parts if necessary.
