Your car's spark plugs are an integral part of your vehicle, and if they are not working properly, your car's ignition system will be unable to start your car. Thankfully, there are a couple of warning signs that you can keep an eye out for to help determine when your spark plugs are nearing the end of their lifespan and should be replaced.
If you notice that your car sounds rough and makes grinding noises while idling or travelling at very low speeds, you may have an issue with your spark plugs. A properly functioning engine will sound smooth and quiet while your vehicle is not in motion, and a rough idle (especially when coupled with excessive vibration) can cause further problems for your engine which can be expensive to fix. Additionally, if you notice that your car is misfiring suddenly or constantly, you should have your spark plugs checked, as your engine is unable to operate properly, increasing the amount of strain on your engine and exhaust system.
Reduced Fuel Economy
Malfunctioning or damaged spark plugs can cause your fuel economy to drastically decrease. This is because your engine will no longer burn fuel evenly or completely, and rougher operation can lead to increased wear on the engine itself. If you notice that your fuel consumption has risen significantly without a corresponding increase in your driving distance or change in your habits, you should head to a mechanic to have your spark plugs looked at.
Damaged or worn spark plugs can also reduce how well your engine is able to increase the speed of your vehicle. If you notice a sudden decrease in the responsiveness of your acceleration pedal (long delays before accelerating, sometimes coupled with excessive noise and grinding), your spark plugs are likely the problem.
Probably the most obvious sign of failing spark plugs is having trouble starting your vehicle. If it takes several tries before your ignition system is able to catch and turn over the engine, your spark plugs are likely worn down to a point of near failure. This problem can be aggravated by cold weather, which makes it harder for the ignition system to catch in the first place. It's a good idea to have your spark plugs looked at if you notice that it has become difficult to start your vehicle on two or more occasions.
