The problems could be that a plug was not gapped correctly or needed to be gapped and was not. Easily the best thing to do would be to remove it and check it to see. Visit your local Autozone as well and have the codes read, if there is indead a misfire, there should be a code that will tell you in which cylinder exactly the misfire may be coming from. If the spark plugs are not causing the problem, then you can retrace you'r steps and check the plug wires or coil.

Hope This Helps!
