i've been fighting some ABS and bad idle problems lately to no avail. today my ANTILOCK light would flicker and go on and off when drove over large jarring bumps. as the light would flicker, the engine would hesitate a little if i was accelerating and the voltage meter would spike and drop wildly. this sounds to me like the OVP. is there any chance that a bad wheel speed sensor (possibly a short in a wire or harness) could cause the OVP to kick on and off?

thanks
