I was looking under the hood, and noticed that i could hear air rushing around. I found that a vacum hose had decayed and cracked. After i replaced that, everything has been fine

Check your vacuum hoses (They are 3/8" Rubber hosing on the right side of the engine, you will need to remove the air intake piping (Also remove the throttle body to make accessing them easier) This is the #1 cause of high idling in the 3.0 OHV and 3.0 DOHC sable engines.

I am having the same issue after I changed my battery today. Upon doing some research it seems like there is some way of aiding the computer with proper idling. I haven't done it yet... plan on going to the dealership where I got the battery, but from my understanding you disconnect the negative line from the battery for a few mins, reconnect, and then apply gas at 3000 rpm for a few mins until the fan kicks on. AND this will help reset your car to proper idling. Good luck
