I don't know if this is it or not, but years ago my wife's car did this. It ran fine the day before. It turn out to be the catalytic converter was clogged up. Try putting your hand near the exhaust pipe and see how much exhaust is coming out. Good luck. Are you getting P0171 and P0174 'check engine' error / trouble scan codes? (indicate a lean condition Bank 1 and Bank 2, respectively)
See "Related Questions" below for another possible cause, that involves leaking intake ports.

TC (short for Traction Control) is designed to prevent loss of traction of the driven road wheels, and therefore maintain the control of the vehicle when excessive throttle is applied by the driver and the condition of the road surface (due to varying factors) is unable to cope with the torque applied. You may have turned it off and it is showing you that its off or you may have a faulty TC.
