I just got a 95 millenia s. When I drive it for a little while, the "tcs off" light comes on randomly and stays on until I turn the car off. When it comes on, also, the car starts jerking and it won't go past 70 mph. Also when I try to go up a hill, the speed starts dropping with the "tcs off" light on. Why is this? If someone could please help, I would really appreciate it. Thanx.
