This would be the forth cylinder from the front(where the pulleys,and belts are).There will be a coil,and under the coil,is a boot,connected to the spark plug.The miss fire could be any,of the three.I would replace the spark plugs (all four)and the boots.Then if the miss fire is still there,replace the coil,on number four cylinder.

If the engine is still not warmed up yet and you take off like a bat out of hell, they will misfire occasionally. If it is a frequent problem change the spark plugs.
