What are the perfect solutions for Haval h2 jitter?

The following is the perfect solution for Haval h2 jitter: 1. Haval h2 jitter is caused by dirty throttle or too much carbon deposited in injector, which makes the combustible mixture of engine thin and thick, leading to idle jitter after cold start. The quick solution is to clean the oil circuit and check whether there is carbon deposit in the idle motor, which should be cleaned. 2. Haval h2 jitter is an ignition system failure. Spark plugs are wearing parts and need to be replaced regularly. If too much carbon deposit or too large ignition gap is found, it needs to be replaced. In addition, check the working conditions of lines, high-voltage lines and ignition coils. The automobile computer can be used to determine the state of the ignition system.
