- Testing a spark plug involves several steps. Firstly, it's essential to disconnect the spark plug wire from the plug and ensure the engine is cool. Using a spark plug socket and ratchet, remove the plug for inspection. The color and condition of the insulator tip can provide valuable insights. A light brown or gray color indicates proper combustion, while white may suggest overheating, and black could mean rich fuel mixture.
