What could be a potential cause of running issues in an ignition system?

Wear in an ignition system can lead to running issues because the various components of the ignition system, such as spark plugs, ignition coils, and wires, can degrade over time with use. As these components wear down, they may not function as efficiently as they should, which can result in weak or inconsistent spark generation. This, in turn, can cause misfires, poor acceleration, or overall engine performance issues.

While other factors like faulty battery connections, incorrect fuel types, and exhaust blockages can certainly cause issues in engine performance, wear represents a more chronic problem that develops gradually, leading to diminished spark quality and reliability, ultimately affecting the engine's ability to run smoothly. Understanding the effects of wear helps technicians recognize when components need maintenance or replacement to maintain optimal ignition system performance.
