Starting a couple of weeks ago, my 02 Rendezvous has been acting up. Usually right after I start the car, and make the first turn and brake, the brakes will pulse in an ABS fashion, and the traction control light kicks on. 95% of the time, it's only right after I start the car. Occassionally I'll get an ABS pulse when braking. Can someone tell me what might be wrong, and how to figure it out? From doing a little investigation on the web, it might be some sort of ABS or speed senor. Thanks!
