Problems with the spark plugs and ignition coils?

The ignition coil converts the vehicle's 12-volt battery power to high ignition voltage, transferring it to the spark plug. Then the spark plug ignites the gasoline-air mixture in the cylinder, driving the engine. Each cylinder has a spark plug; some cars, like Mercedes, have two spark plugs per cylinder. Injection valves inject fuel into the combustion chamber. Share your issues and experiences with the community to learn more and connect with others.
