Surging?

My 1988 Ford Mustang 5.0 recently has started bogging when I start up the car. The idle goes up and down and will die unless I keep giving it gas. This is happening before I even put the car in drive. Once in drive it will idle up and down and almost die until I drive it around for maybe 5 -10 minutes.. then its fine, no problems at all. This happens when the car is sitting at a light or sitting in park. If I drive the car around.. park for like 10 minutes or so, then start it up again and drive, it seems fine. It seems to happen only if the car is sitting for a few hours or so. After I drive it for a few minutes after starting it is fine. Even at stops it idles perfectly. Just happens when I first start the car after awhile.

I hope any of this made sense and someone can give me thier input!

Does anyone know the answer to this one? Idle Control Valve maybe?

Should I start a new thread?
