High idle problems are often times related to vacuum leaks or lean fuel conditions. I would start by checking for vacuum leaks and other fuel delivery components, such as the mass air flow sensor, injectors, throttle body, etc. High idle problems can also be caused by faulty or damaged spark plugs. Try checking and/or changing spark plugs as well. You may also want to run a fuel injection cleaner through a tank of fuel as sometimes something as simple as a dirty injector can cause a high idle or surging idle problem.
