Pulling in the front of 02 Mustang

[MissBlondie]

Okay, I've noticed in the last month that when I break in my stang to make a complete stop, it feels like the whole car is going forward. Like the engine is almost moving forward after the car is stopped (that's a lil bit of an exaggeration), but gives you the idea of what it's doing. I bought this brand new in the end of July, zero miles so it hasn't been beat on, and didn't notice it till late August. Is this something that I should be worried about or is it ok??? Why is it doing this??? Any help would be greatly appreciated! (by the way its a 2002 v6 auto stang)

Thanks- Jill
