Hi,
The reason you feel a misfire when the light is on is that the computer reduces power to prevent a tire from spinning (hence traction control).
Based on what has happened, I suspect either the wheel speed sensor was damaged or what is called a yaw rate sensor. However, since you mentioned specifically traction control, my first suspect is either the wheel speed sensor or the wheel speed sensor reluctor ring was damaged.
By any chance was the front hub/wheel bearing replaced on the side that was hit? If not, that is my first suspect, an intermittent issue with the reluctor ring.
Also, you have a switch to manually turn off the traction control. If you turn it off, does anything happen? See pic below for the location.
Let me know.
Joe
