Default Idle question

What would cause my idle to increase as the car warmed up. I set the idle with the car warm and the choke held open to 800rpm. Like the manual says. Lately when the car gets to operating temperature the idle is hovering about 400rpms faster. What would cause this? It idles right around 800 when its warming up. Should I reset the idle for operating temperature? And if i do that wont the car stall when its warming up?

Default Are you running a Q-Jet?

If so check out this thread. Lars sent me his paper on setting up the choke and it fixed things for me.
Well actually, after reading the paper and setting it up per the instructions it was fixed.

There are 2 separate idle speed screws: One for cold idle (fast idle) and one for hot idle (idle speed screw). Set the two separately.
