Now don't quote me on this as I'm still learning my own motor but I know that like on my Dakota I have a IAC sensor which if it went bad would cause a high idle when you first start the vehicle so if our cars have them which I'm not sure of yet then thats where I would look first. At most its like a $30 part from Advanced.

When your battery died your PCM was reset.

recharging battery
I had to jump start once and while the battery was charging itself back up the car was idling between 2500-3000rpm. No problem, just annoying when you have a loud car and everyone is looking at you like a ass, "what you want to race my corolla?"

Normal. Just trying to learn short term idle trims again since you erased them when unhooked the battery to replace. Give it an hour.
