runs rough when cold

I just purchased an 88 lx 5.0 5sp. I noticed that when its real cold(like just after startup) and I roll into the throttle it really hesitates and pops. But after 2 minutes or so it goes away completely. This is my fourth mustang (2nd SD) and I have never experienced this, any ideas.
