If you are in a cold place, the air intake will get so cold that ice will form on the idle control valve and the engine won't maintain an idle without help, until the engine gets warm enough to prevent the ice from forming. I have a K&N Filtercharger air intake system on my 1993 GC and it does this on a regular basis. It is a PITA, but not a serious issue.
