My 2000 Deville started running rough/ I pulled the codes and it said I had a misfire on #2.What would be the likely cause? The car has 135000 mile and the sparkplugs were changed at 10000 miles

The most likely cause of the problem is either a bad coil or bad/plugged injector the best line of action is to switch one coil with another and see if the problem follows the coil if it does the coil is the problem.
