It means random/mutiple cylinder misfire detected. Sounds like your in need of a tune up. When was the last time the plugs, wires air filter etc where changed. If it has been awhile maybe it is time to do a tune up. Then see if the code comes back.
PS Next time please included year, make, model and mileage of car. It will make things easier.
