What is the reason for the unstable idle speed of Changhe Suzuki Liana hatchback?

It is possible that the throttle is too dirty and there is too much carbon deposited in the nozzle and air inlet. In the case of cold car, the carbon deposit will adsorb some fuel. If the fuel does not completely enter the cylinder for combustion, it will cause the symptoms of unstable idle speed and difficult start. Solution: Clean the throttle, fuel injector and air inlet. But consumers should be reminded that the cleaning work can be done step by step. Wash the throttle first and see if it improves. If it is good, the remaining two items need not be cleaned.
