I would guess it means you have a misfire and a lean mixture.
Check/replace your spark plugs and wires.
Drive for awhile and get it re-scanned for the AFR mixture. Could be an O2 sensor if it hasn't been changed in 50-60k miles.

If you have the actual code numbers we can look them up in techinfo and someone with an FSM can tell you the diagnostic steps you could take besides the ones recommended by Willwren

If it smells like its running rich then you might want to check for a vacuum leak or an exhaust leak before the O2 sensor. Both can cause a lean code due to the extra air and the computer will try to compensate by richening the mix.
If its not running rich then I too would go for some good fuel injector cleaner in the tank before replacing the O2 sensor.
