Try this: Remove the rubber pipe that goes to the throttle plate at the end of the intake manifold. Open the throttle flap valve and inspect the interior for excessive carbon buildup (black gunk around the flapper and the outer circular bore)...If it is dirty, get some carb cleaner & spray the daylights out of it until it is clean clean clean. Reattach the tube and start the engine, it will smoke quite a bit until all of the cleaner in the intake is digested by the engine. This should improve the idle. What may be happening is the black gunk may not be letting the throttle valve to close fully, and WILL keep the idle up.

Probably the "idle speed controller",(the ecu is programmed with target idling speeds values to respond to different engine conditions, coolant temp, a/c on/off etc,sensors transmit signals to the ecu which controls the flow of air through the bypass of the throttle valve and adjust idle speed top target value)
however this what the manual says,
check for defective throttle linkage or cable
check idle up-up vacum switching valve
check coolant temp sensor
check throttle position sensor.
Usually if its major, then the check engine light comes on,
