Your Toyota vehicle requires ignition in order to start at your command. That happens in large part thanks to the spark plugs, which provide the initial flash that ignites the mixture of air and fuel inside the engine.
How Spark Plugs Work
That flash is generated when the spark plugs fire an arc of electricity across a gap between the two leads in the plug's head. Those gaps are calibrated to provide the ideal spark needed to kindle the mixture inside the combustion chamber, leading to your engine purring to life.
How to Recognize Failing Spark Plugs
Eventually, though, your spark plugs will begin to become less effective. Maybe they've become corroded. Perhaps the gaps have grown too wide to produce an effective spark. Signs of problems include:
- Your engine begins to misfire
- You have trouble starting your vehicle
- The engine idles rougher than usual
- Your "Check Engine" dash light comes on
