The clicking sound is likely your BOV. The BOV is stock correct?

Idle oscillation is typically reproduceable under similar environmental conditions. What you are describing is a bit radical. If the mixture is close enough to correct that it idles smooth 90% of the time you should be able to calm it the other 10% by braking with the clutch out until the engine is pulled down to <1500rpm. From what you are describing I'll bet that won't work, so something else is at play.
