Default 03 gt sputtering problem??

hey guys i was wondering if you culd help me out with a problem im having? my car is a 03 mustang gt auto. when in park the car sputters when i step on the gas and when its in first gear does the same as soon as it shifts to 2nd i got all my power back... weird? i just got the car a couple days ago and i noticed the traction control light stays on whitch im assuming it has a tune on it.. but the other night i was riding in it and on the dash the green spin tire light came on and it acted normal?? any ideas thanx for all your help

i would check the coils packs too. i had a misfire in cyl 1 because my coil pack took a poo.
does the check engine light come on at all?
