Could you give us some details like what year the car is, how many miles, anything else wrong with it.

If you have an 02 sensor out, I'd start there. It will be messing up your A/F ratio - which can lead to rough firing, poor performance and poor fuel economy. I'd look at thecrank sensor and the cam position sensoras well asap. Could be sensors out, which is a quick fix. But if the sensor is reading a real oops - I wouldn't drive it until I got it fixed. If you get it firing with incorrect timing, it'sa good way to need a rebuild.
