this happened to a guy dave i know with his SVT. Turns out that on the 98+ contours the traction control was programmed into the PCM...worked by pulling fuel/spark, making for quite na unpleasant ride taking his tour around the track. I dunno how it got enabled on his car...but I think the only way they fixed it was by replacing his pcm or soemthing. If I hear from him soon I will ask for sure.
