Traction light coming when idling, upon acceleration feels like a hard shift. on 2008 Pontiac G6

When I stop at red light after a few seconds traction light comes on, the car starts to feel like its going to die and traction light comes on then when I take off the car feels like it does some kind of hard shift then its fine again until next stop sign or red light, and check engine light stays on all the time

Need to get the codes read and post results to further assist you. Autozone will read the check engine codes for free. It is possible a caliper has frozen up and is dragging on the rotor. This will make it harder to accelerate and will burn up gas more quickly.
