Default Stalling in cold weather. Air Idle Valve?

I replaced my air idle valve a few years ago. Ever since then I've had problems with the engine dying in cold weather. Whenever I let off the throttle(at lower speeds) the RPM's drop to zero on the tach. Most of the time the engine starts back up after a half second or so, sometimes the engine dies. It only does it in colder weather. I've never noticed any problems in the summer. The truck runs great otherwise and Idle's fine any other time. It started doing this after I replaced the air idle valve.(years ago) I have adjusted the plunger on the idle valve in the past and I have noticed a slight change in idle RPM's, but they still drop after letting off the accelerator. Could the cold weather be causing the valve to gum up and be slow to react? (I am assuming it is closed when you are on the throttle, correct?) Any ideas? Any help would be appreciated. I have a 97 Ram with a 360.
