Your not supposed to ever adjust the factory set throttle plate adjusting screwing. The computer control's the idle do you have any code's?Most of time when you have a high idle it's caused by a vacuum leak what rpm does your car idle at?I would check the S shaped short hose that goes from your intake manifold to your pcv that sits in your valve cover. They get hole's in them and leak vacuum and cause high idle's.
