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.

It"s in warm up mode , the computer is giving it more gas for fast idle to warm up...when you try to give it more gas to move you are giving it more gas then the plugs can burn...just let it warm up till operating temp
