We dont have plug wires on new edge cars.
From what I can tell from searching 3 or 4 forums this is a common problem with the 99-04's. No one really has an answer. Some guys have full tuned, blown, built motors and still have the slight miss around 1500 rpms.
Some people say its the tune that ford put in, but theres other people with new tunes that still have the problem. So far I've never seen anything bad come out of it, mines done it since I bought it also. I'll look around for a few of the thread I was talking about and post them in here later.
