Check the idle air valve. Also a vacuum leak will cause high idle. Another possibility is a faulty coolant sensor throwing things off, but usually that'd cause issues elsewhere too. Only other thing would be MAP sensor or EGR flow being messed up, but those would also cause issues beyond idle speed.
