The car is not running at the best possible fuel and air mixture and has less efficient gas mileage than normal. You should go see a mechanic and get a complete diagnosis to determine why the problem did occur in the first place. Some other issues related to this code are improper acceleration, problems in starting, and rough idling of the car. The problem may also be due to faulty O2 sensors and can be determined accurately after an inspection. You can drive a car with these issues, but it is advisable to get them fixed before driving on longer routes.
