I did a stock engine swap and now the car has a bad idle.

It runs good when you get on the gas but at idle its bad so would I have to bring it to a dealer for them to do something with the computer?

Might just have to relearn the idle speed due to battery disconnection during the swapping

How could I get it to re learn the idle by driving or just let it run for awhile?
