Hey Lykkers! 👋 Have you ever struggled to start your car and wondered what's going on? I've been there, and most of the time, it's because of worn-out spark plugs.
These little parts play a huge role in getting your engine fired up. Let me share some simple signs that told me it was time to check mine before I got stuck somewhere! 🚗⚡

What do spark plugs actually do?

Spark plugs create the tiny spark that ignites the fuel in your engine, making your car start and run smoothly. When they get old or dirty, that spark weakens, and your car might struggle to start or run rough. It's like trying to light a fire with damp wood – it just doesn't work well!

Signs your spark plugs are aging

Here are some clear clues to watch for:
• Your car takes longer to start or feels like it's hesitating
• Engine misfires or rough idling (it shakes or sounds uneven)
• Reduced fuel efficiency – you notice you're filling up more often
• Strange engine noises or vibrations when driving
• You see a check engine light on your dashboard
If you spot any of these, your spark plugs might be on their last legs.

My experience with spark plug trouble

One day, my car started feeling a bit off. It took a few tries before it actually started, and the engine was rough for the first few minutes. I ignored it at first, but then the check engine light came on. After a quick visit to the mechanic, they replaced my spark plugs, and wow — the car was like new again! Starting was smooth, and the engine sounded great.

How often to replace spark plugs?

Most cars recommend changing spark plugs every 30,000 to 50,000 miles, but it depends on the type and driving habits. If you drive a lot in stop-and-go traffic or in harsh conditions, it's a good idea to check them sooner.

Tips to keep your spark plugs healthy

• Follow your car's service schedule
• Pay attention to how your car starts and runs
• Don't ignore warning signs like the check engine light
• Have a mechanic check your plugs during regular maintenance
