changing weather from fall to winter (esp. if you live up north).
Values don't change in the cells. Environment and mechanical issues (O2) are the only things that can make a tune seem "off")

Forever, weather may play a variable. Remeber tuning is done during certain conditions when conditions change it may change your tune a little. shouldnt be to a degree of worry though.

I was also under the impression that tunes lasted for the longevity of the car. (Barring mechanical failure, or drastic change in weather conditions.)

I would guess your front o2 if that's the code your pulling. If you are set to idle off of o2 feedback (closed loop) and your o2 goes bad it will affect your idle. If they have you set up in open loop at idle I would do a battery reset and let the iac try to learn the idle again.
Is your rpm changing/ bumping around when your AFRs do that?
And once you figure out the fix...PLEASE POST WHAT WAS WRONG!!! That way the community can learn. Incase someone has an issue like this
