First thing to do is change the spark plugs if you have over 100,000 miles and they haven't been changed. Pay particular attention to the spark plug boots and wires and replace if necessary. Next I would clean the MAF sensor. Rowefast is correct in that all the things he listed and more can cause random miss fires.
