Drive it would be one solution. Engines aren't designed to be idled for three minutes after start up.
It's probably hunting because of an incorrect mixture, usually weak, for one or a combination of several reasons.
Injectors long overdue for a service? Pattern 'blue' sensor' not 'tracking' resistance against temperature as intended, minor air leaks, etc.
