Damon - Sounds like you need to clean your throttle body. Even a small amount of deposits there can severely confuse your automatic idle control. Take off the plumbing just ahead of it, open the throttle and hose down the inside of the throttle body with good carb cleaner (pref. something with Techron). Scrub with an old soft bristle toothbrush, esp. around the butterfly. Then, confirm that your throttle position switch is working correctly - giving proper electrical output AND not binding or hanging up the throttle valve. And yes, you'll need to something about the melted hose. That should be done first, before anything else, and figure out what caused that so it doesn't recur.
Good Luck.
