ABS question

[Z Ya Later]

Ok, here's an update. Now, since its colder, the ABS INOP light is coming on just about every time I drive her. However, it never comes on immediately. Most of the time it comes on while I am driving, the first time I shift into 2nd since starting her, or when I hit the brakes for the first time after going faster than ~10mph. I've noticed in the past that the INOP will also come on sometimes when I have a "spirited" drive in her (in other words, when I let her open up lol). After thinking about what Fred said, this has got me thinking that maybe the rear sensor is throwing the EBCM off and making it think that the front sensor is the problem. Is this a possibility? Thanks guys.
