so i was working on the front suspension and i remember hooking everything up right. tonight on my way to my girlfriend's house the "anti lock" light was on and wouldn't turn off. on the way home it was off, but every time i come to a stop (2-5mph) i can feel the abs system kicking in. any ideas why? it doesnt come on when i slow down hard at high speeds, just normal breaking at low speeds.

abs going off at low speeds?

I'm going to guess that the light comes on when you switch on the ignition, goes out when the engine starts, and then comes back on while the car is moving. The behavior is consistent with there being a bad wheel speed sensor. To find out which is bad, disconnect all but one sensor and then drive the car a bit. If the light comes on that sensor is good. Repeat for each of the other sensors until you find one that won't cause the light to come on and you'll have found the bad sensor.The car makes it possible, but the driver makes it happen.

The same thing was happening to me. This was a couple of weeks after installing H&R race and bilsteins. I bled the brakes over the weekend and when I took off the drivers side front wheel I noticed that the housing for the wheel speed sensor cable was partially worn through. I must have not tucked the wires out of the way enough.
I wrapped up the exposed wire in electrical tape and zip tied the wires to the strut out of the way.
So far no abs light and no bad symptoms.
I guess the point is to check the wheel speed sensors as others have mentioned.
