i have and 89 bronco II that when i fire it up idles for a minute then revs itself to 2k and then idles again and will do this randomly as long as i let it idle... if i drive it however, then let it idle it will do so normally for about 10 minutes then it will start to rev itself randomly again... any idea what could be causing this?
