What is the reason for high idle speed?
Too high idle speed of cars is mostly caused by carbon deposition in the engine, and it may also be caused by throttle damage or air leakage in the air intake. If the idle speed is high in the morning, then this is normal. Because the water temperature is low, the computer will inject more fuel, so the idle speed will be higher.
