When first turn on or anytime the car is cold the idle goes crazy up & down up & down. When i put it in gear it goes away.

a common problem with a hunting idle cold is a vacuum leak. Is your "check engine" light on?

you should leave your vehicle at a shop over night and have them scan it first thing in the morning so the can view the scanner data when the idle is jumping around.
