ABS System

I got a 94 sedan deville. The cars ABS light was on when I bought it. I reset the computer, now when I start the car, no abs light is on but I cant get the car over 10 MPH? When I push on the gas it says traction enabled and slows me way down. I can keep pushing gas but traction control takes over and slams on the ABS. After about 15 min of getting motion sickness.... It shuts off and the light comes on and says traction disabled and works fine...no abs.. Is this an easy fix..Any help would be greatfull

My car does the same thing... My traction light and abs lights are on, I usually shutoff the traction and it works fine but the lights are always on. But no idea what is causing this, I was thinking maybe one of the speed sensors on the wheels?
