What constitutes a tune-up for an engine with solid state ignition?

A tune-up for an engine with solid-state ignition primarily focuses on the components that directly influence engine performance and efficiency. Replacing the spark plug is crucial because it is the component that ignites the air-fuel mixture within the combustion chamber; a worn or damaged spark plug can lead to poor engine performance, hard starting, and increased exhaust emissions.

Decarboning the head is also an important tune-up procedure because carbon deposits can accumulate on the combustion chamber, valves, and piston, impacting the engine's ability to breathe and perform efficiently. By removing these deposits, the engine can run smoother, and power output can improve, leading to better fuel economy.

While other components like the solid-state module or ignition charging coil are part of the ignition system, they do not require regular replacement as part of a tune-up unless there is a specific failure. Therefore, focusing on the spark plug replacement and decarboning aligns with best practices for maintaining optimal engine performance in solid-state ignition engines.
