If the engine's idle speed is set too high, what direct consequence does it have?

Question

DentroTest · Accepted Answer

Idle is the minimum revolution speed at which the engine runs stably without pressing the accelerator. If it is misadjusted and the engine turns at more revolutions than those recommended by the manufacturer, it burns more air and fuel mixture unnecessarily during stops (at traffic lights or in tailbacks) and consumption increases. Saying that more speed is reached is incorrect, because idle does not affect the power or the maximum speed of the moped. And saying that emissions are reduced is false, because consuming more fuel also generates higher emissions.
