When does a car have to relearn idle?
The relearning process depends on the PCM. Engine idle refers to the lowest rpm or speed at which the engine turns over when the driver is not depressing the gas pedal, according to 2CarPros.com. At idle speed, the engine generates its lowest emissions, thus conserving fuel. Idle speed that is too low can stall an engine.
