won't idle

[kcroadrocket]

well, not exactly...it will start and idle fine in warm weather and will also start great in cold weather, but it won't idle in the cold weather. sometimes it won't idle right for some time and at other times after the engine warms up, it will start idling fine. it's not throwing any codes.
yesterday i drove for about an hour and it still would not idle, died at every stop light. then i got home, let it set for about an hour and it started and idled as it should.
any ideas?
thanks.

Could try cleaning the IAC valve. Pretty easy to do. A search should net you a how-to thread

Either the IAC or it needs new upper intake seals. They are just big O ring like seals and it isn't a big deal. 2 hours in your driveway.
