A/F Ratio going crazy, check engine light on


Well I just bought a 96 4.6l and right now the A/F ratio gauge is acting funny, when cruising it goes from optimal to rich back to optimal and so on... my check engine light is also on. I'm thinking it could possibly be an O2 sensor somewhere... because I'm not sure if the previous owner got mil eliminators (I have straight pipes back from the 2 front cats... or what I think are the front cats) I'll hopefully find out the code today at autozone or something.

Any ideas?
