It could be plugs, injectors, or a false code. If you havent had a tuneup in a while, it'd be a good idea to go ahead and replace the plugs, fuel filter, and run some fuel injector cleaner through your gas tank. Sometimes even going over a bumpy road can throw a mis-fire code so I wouldn't get too worried just yet. I'd do a tuneup and reset the codes, or just reset the codes if you've recently done a tune-up. If problem persists then be worried.

You can also disconnect a vacume line if you have the proper pump and run the injector cleaner straight through the injectors. Thats what I had done. I did that, changed the fuel filter, the oil and oil filter and the air filter all at once and the car ran really good that night at the track.
