Freaky warning lights!

[stoned_pimp420]

My 90 model buick century 3.3L V6 DOESN'T have traction control or antilock brakes, but the dash warning lights keep coming on, Low Trac light comes on just driving down the road and the Anti Lock light comes on just about every time I get on the brakes lightly whenever I stomp the brakes or have to mash the pedal rather hard the antilock light cuts off. I'm kinda stumped on this problem. It hasn't caused any problems that I can notice so far but at night both of those lights are pretty bright and will annoy the heck outta you. any one else ever even heard of this happening?

My car was doing something similar to this, turned out it was the ignition switch going bad, tripping the anti-theft system. After replacing the ignition switch (had it done by a Buick dealer), it fixed everything.
