Default TRAC light comes on when driving on freeway
Hi everyone,
I'd just clean out my throttle body the other day. Then as was driving on freeway doing around 85 to 90mph my TRAC light comes on but the car was running fine until I come to a complete stop, then engine sorta sputter and the idle become unstable. But after I turn off the car and restart it again, the light was gone until I'm on the freeway punching the gas. I don't know what wrong with this. Please help me somebody. Thank You.

well, since no one reply to my post. I took the car to the shop and they found out that it was the TPS that caused this problem. Just want to let guys know if someone have similar problem as I do
