First get the computer scann for codes. This vehicles' computr keeps a record of cylinder misfires and could tell you which cylinder is causing your problem. Once that is determined you'll have to check the spark plug, ignition coil, and spark plug wire (if equipped) for that cylinder.
If you still can't find the problem, have a compression check ran on that cylinder.
Don't forget to check for vacuum leaks which could be exclusive to that cylinder, causing the misfire.
