What is Bora's idling jitter?

It is because of serious carbon deposition in the engine, ignition system failure, abnormal oil pressure and aging of engine parts. The most common cause of vehicle jitter is that the throttle is too dirty or there is too much carbon on the nozzle. There is too much carbon deposit in the engine, the gasoline sprayed from the coolant nozzle is absorbed by the carbon deposit, and the mixture sprayed from the coolant is thin, which makes it difficult to start. Only when the gasoline absorbed by carbon deposits is saturated can you get on the bus. Ignition system failure: check the working conditions of spark plug, high voltage line and ignition coil. Even if the ignition system can't work normally, there will be a bad spark ignition state. Check whether the spark plug has too much carbon deposit, and if so, replace it. Unstable oil pressure: after cleaning the engine carbon deposit, throttle, replacing the oil pad and spark plug, if the body is still shaking at idle speed, it is recommended to go to the 4S shop to confirm whether the oil supply pressure and intake pressure sensors are normal. Abnormal or incorrect fuel supply pressure and improper operation of intake pressure sensor may cause vehicle body jitter. The solution is to check the oil pressure and replace the parts if necessary. Million car purchase subsidy
