PURPOSE: A method for controlling ignition timing is provided to improve a response to sudden acceleration, and to stabilize an engine by optimizing recovery timing to basic ignition timing when releasing sudden acceleration. CONSTITUTION: A method for controlling ignition timing comprises the steps of: determining whether the state of a vehicle is the condition of sudden acceleration while the start of an engine keeps on; calculating an acceleration fuel amount related to an introduced air amount and an offset air amount if the state of the vehicle is the condition of sudden acceleration; and applying the fuel amount related to the offset air amount to the acceleration fuel amount, and deciding ignition timing according to an engine rpm.
