Default check engine light

my check engine light goes on and off, I had the o2 sensor replaced, and the light went off until the computer reset, then came back on and stayed on for two weeks, then shut off for three weeks, then came back on and is staying on, I have changed the air filter and spark plugs, any idea what I need to check now?
