You have to take the reading in 'closed loop' mode to be meaningful. The o2 sensor reading should then swing up and down between .45 volt very rapidly. O2 sensor signal is not considered at idle.

Do a basic tune-up, then go to the emissions stations with a fully warmed engine, and post your results here if you fail. It's easier to tell what's wrong and what is likely to be the cause.

If you fail emissions, then you can go back free of charge to get checked again (that's how it is in Ma, don't know about your state though)
