I recently purchased a 2003 Mach 1. I noticed today that the ABS light come on and stayed on and also the traction controll wouldnt turn on. The more that I watched it I started noticing that the ABS light would go off and traction control would come back on if I went over a small bump or something like that. I really believe that something is just loose but I have no idea where to start looking. If anyone has any ideas I would greatly appreciate them.
