ABS Light on.
ABS activated at above milage. Very annoying when starting car

ABS started malfunctioning, pulsing as soon as I touch the pedal (under 5mph) and would even pulse without touching the break pedal. Then ABS light appeared, which was due to a faulty wheel hub. Replaced the hub and the ABS light turned off, but the pulsing problem still exists. Only an issue under 5mph, but it pulses every time. For example, rolling up on a stop sign, as soon as its nearly stopped it will start pulsing
The light is on and I am not planning to fix it at this point.
ABS light is on all the time.
I own a 1994 Buick LeSabre. I purchased the car brand new on 10/31/1994. It has always been maintained very well; however, my ABS - Anti Lock idiot light just came on.
