The same thing has happened to me when I first start the car after not having driven it for a few days. I always just figured it was normal.

this happened to me once. i just pulled off the battery tabs, and took out the 7.5 amp fuse. then turn on the headlights to make sure there is no power left in the system. and it should straighten it's ass out.

as it did for me

IACV was probably stuck, or moisture in the vacuum lines most likely the culprit is the moisture though.

Do you have an aftermarket intake? If so, its most likely the IACV (Intake air control valve). Check and make sure your filter didn't fall off the end of the intake and suck some debris up.
