If you replace your spark plugs when needed, your vehicle is going to be in better overall shape. If you hear noises that sound like knocking, pinging, or rattling, it could be a misfire of your spark plugs. If you need new spark plugs, the engine may sound rough when your car is idling, or you could feel as if your vehicle is vibrating.

If you have an engine that seems like it’s misfiring or hesitating and just generally not operating smoothly, it may be because of the spark plugs. Your car may seem like it’s performing sluggishly if you need new spark plugs. This can lead to other issues as well, including problems with acceleration. If that space is too far apart, there are problems with combustion. As a spark plug gets older, there’s a wider space because of wear and tear, debris, and extreme temperatures. When a spark plug ignites, it travels across a gap or space to provide just the right combustion at the right time. The reason for the link is because spark plugs spark combustion in your engine. If your spark plugs aren’t working optimally, then your gas mileage is going to take a hit.

If you notice a decline in your vehicle’s fuel economy, it could be the result of spark plugs that are either old or dirty.
