Subtle High pitch whine?

[DenverSteve]

Any newly discovered sound should be checked out by your dealer. I would never trust any unusual sounds as "normal" until you've had my mechanic tell me personally that it was okay. You're the only one who will pay if there is a problem developing.

Could be the SAI system, tends to run more in colder weather to reduce start-up emmissions.
My whine was fairly noticeable, but ceased immediately upon ejection of the ex-wife.
