Off to a Rough Start

It's a given that your car should start right up and continue to run flawlessly whenever we need. But the fact is that a combustion engine is made up of a multitude of systems and components, many of which are subject to wear and tear over time.

If you're having hard starts on that Chevy Silverado 1500, noticed a rough idle on your Honda Accord or your check engine light has illuminated and then gone off or is brightening and dimming, it's not just gremlins. You may actually have ignition issues. Since these symptoms are often confused with spark plug issues, make sure you use a scan tool to run a diagnostic check in your engine as soon as possible to find out the exact cause.

Sometimes you can replace a single coil or the entire coil pack in the case of a general misfire code. Either way, don't feel tempted to chalk it up to engine gremlins. Ignoring these warning signs will lead to further reduction in performance and acceleration plus degrade other parts of your engine.

Exciting Current Events

The job of your ignition coils is a very important one that is frequently overlooked. Ignition coils use induction to transform volts from your vehicle battery into a strong current that creates a spark in the spark plug. The spark ignites the fuel/air mix in the combustion chamber, which powers the piston downward. The coils on some vehicles connect to the spark plugs via wires, while others sit directly on each plug. This coil pack is known as a coil-on-plug style.

If you think you may have a bad coil or a bad coil pack, you can test your coils for failure. If it's time for a replacement, you can shop NAPAOnline for a wide range of replacement ignition coils and parts like ignition coil kits, coil straps, coil brackets and more. We also specialize in other ignition and engine management parts like spark plugs and plug wire sets, as well as ignition tune-up kits that can help you get rid of any electrical gremlins and get your engine back to peak performance.
