How to solve the problem of high idle speed of Swift?

1. Change the oil. \x0d\ When there is a problem with vehicle idling, first check whether it is time to change the oil, and the oil should be changed in time, otherwise the engine will be abnormal if it takes too long. \x0d\ Pay attention to the selection of engine oil. Automobile oil should be advanced, such as SJ grade or above. This kind of engine oil has better quality and good performance in all aspects. \x0d\2。 Look at the antifreeze in the water tank \x0d\ The antifreeze in the water tank should also be checked more, neither less nor more, otherwise its effect will be affected, and it will not have a good cooling effect on the engine. \x0d\ Pay attention to antifreeze. Generally, new cars need to be replaced every 2-3 years, or the antifreeze should be replaced every 40,000 kilometers. The antifreeze with suitable freezing point should be selected according to the regional temperature. For example, if the lowest ambient temperature is-10, the antifreeze of -25 should be selected. \x0d\3。 Check the engine. \x0d\ If the idling of the vehicle is not caused by engine oil and antifreeze, check the engine to see if there is something wrong. \x0d\4。 Check the oil circuit. \x0d\ Sometimes the idle speed of the vehicle is too high, and it is likely that there is something wrong with the oil circuit, such as a blocked throttle.
