Spark plug performs a huge job in delivering a vehicle’s power, performance, dependability, and fuel efficiency and, should be replaced periodically. A spark plug can fire 400 times per minute per cylinder or 1,600 times a minute on a four-cylinder engine.
If you find any of the following symptoms, have your vehicle checked to prevent more costly problems from developing.
- Rattling, pinging or knocking noises. When spark plugs begin to misfire, you may see unusual noises from the force of the pistons. Also, combustion will start not working properly. If the spark plug fires at the wrong time, this causes constant rattling, pinging or knocking sounds.
- Hard vehicle start. If there is an issue starting or just feels disjointed and jerky, your spark plugs may not be working right. This can generate misfires and erratic performance.
- Reduced performance. If the generated spark isn’t functioning at 100 percent, your vehicle performance will be poor, and you’ll experience a sluggish and fuel-wasting drive.
- Poor fuel economy. In the case of old spark plugs, fuel is wasted because your car fails to receive the proper, heat-generating spark at the right time.
So, consult your car’s spark plug replacement intervals. Moreover, replace all of the plugs at the same time and with the same type of spark plug that the vehicle was originally equipped.
