Post subject:  96 Volvo 850 hesitating/missing while driving, check engine light on, O2 sensor?

It only has like 63K mi on it. While I'm driving along, especially if I'm on the highway going 60+, I can feel the engine hesitate or miss or something. The check engine light has come on, I had it reset and it came on again, the code was for "fuel mixture too rich"... I know these cars tend to need O2 sensors replaced a lot, but what else could it be? Could it be something really serious, or is it more than likely a matter of it needing a tune up or spark plugs or something? Or maybe a new timing belt? Supposedly it should be replaced at 70K. Any ideas would be appreciated. Thanks.
