How to solve steering wheel jitter caused by unstable idle speed of Liana a6?

When starting or stopping the vehicle without turning off the engine, if the vehicle body is found to shake obviously, it may indicate that the most common cause of vehicle shake is that the throttle valve is too dirty or the fuel nozzle 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 the carbon deposit during the cold start, which leads to the lean mixture during the cold start and makes it difficult to start. In this case, only when the gasoline absorbed by carbon deposits is saturated can it easily enter the car. After getting on the bus, the gasoline adsorbed on the carbon deposit will be sucked into the cylinder by the vacuum suction of the engine for combustion, and the mixture will become thick, and the combustible mixture of the engine will be diluted and concentrated, resulting in idling jitter after cold start. The lower the temperature, the more oil is needed for cold start, and the existence of carbon deposit will affect the smooth start.

Chongqing Taiyi brand car maintenance, efficient engine decarbonization agent, to improve the cold start difficulty, unstable idle speed, increased fuel consumption and decreased engine power.
