Oldsmobile/Buick Repair: 1996 olds/cierra abs/service engine soon light, autozone, fuel tank

Question
I have a 1996 oldsmobile cierra.  Recently the (ABS) anti-lock light has come on.  I had my brakes done in March and have been fine since then.  Any clue as to why the light is on?  My service engine soon light comes on frequently as well, it comes and goes.  I read in the manual that if you change gas stations or let the fuel get down too low it may happen so I am assuming that is why the service engine soon light comes and goes.  Any thoughts?

Answer
NO it is NOT the change in gas or how much gas is in the fuel tank.

Your problem is with one of the sensors for the brakes.

Take your car to any Autozone parts store and they will scan your computer for codes. Write down the codes and the description from the scanner they use and let me know what it is.
