It could be your BISS (base idle set screw) they have an oring and are known to leak on the 4g63t. Also the FIAV (Fast Idle Air Valve) Or just the set screw could have been moved.
But I could help you more if you gave me more detail. As in does it idle that high all the time? Or just when you first start it, does it lope, etc etc.
