High Idle is a classic description of a vacuum leak. If the idle was fine before you worked on it, start by rechecking your work. Often a vacuum leak is accompanied by a slight whistling noise. Check the obvious vacuum hoses. Look at the hose going to the brake booster and the PCV valve. With the engine running sometimes you can just wiggle those hoses and notice a difference.
