An engine misfire may develop due to a failed ignition coil. Our technicians tell us one coil is used for each cylinder. If one fails, often times another is not far behind. It may be worth considering replacing all the coils if a failure is encountered.

My Sorento has been driving a little rough, this morning when I turned the car on it was shaking a bit, when I started to drive the check engine light would come on whenever my foot was on the gas. Brought it to my mechanic, he told me one of my ignition coils were bad and the other 2 were on their way out soon. Replaced the bad one today ($300), next week replacing the other 2 ($600).
