PURPOSE: A method for controlling idling of a vaporizer for an LPG vehicle is provided to control the idling of the vaporizer without the periodic idling control by a driver. CONSTITUTION: A method for controlling idling of a vaporizer for an LPG vehicle comprises the steps of; calculating an intake air amount and intake temperature by applying a map sensor and intake temperature sensor to an ECU at the LPG vehicle comprising an electric valve for controlling the idling of a vaporizer and calculating a duty value for a main duty valve of a mixer according to the calculated intake air amount; opening the electric valve to make the calculated duty value of the main duty valve excess a first duty threshold when the calculated intake temperature is less than the determined threshold temperature; and opening the electric valve to make the calculated duty value of the main duty valve excess a second duty threshold when the calculated intake temperature is more than the determined threshold temperature.
