Hello, Eddie here and I will do my best to help. Usually it's the spark plugs first, and the coils can wear over time and arc out the side of them before they fire the plug, or it's possible it could be a bad fuel injector. Have you had the spark plugs replaced lately? That would be the first thing I would look at.
