It's a good idea to get a repair manual if your going to work on your own vehicle, and it's never been easier or less expensive to get a high quality manual. Try and you can have one in minutes, for less than $30.00. Read up on the job you are about to perform, it will show you what special tools you will need and you will be much better prepared to tackle any job on your vehicle.
High idle is most commonly the result of a vacuume leak. Next time the car is running, pop the hood and listen for hissing.
