The Pontiac Grand Prix is a reliable and powerful vehicle, but like any other car, it requires regular maintenance to keep it running smoothly. One of the most important maintenance tasks is changing the spark plugs. Spark plugs are responsible for igniting the fuel in the engine, and over time, they can become worn out and reduce the performance of the vehicle. In this article, we will provide a step-by-step guide on how to change spark plugs on a Pontiac Grand Prix.
Why Change Spark Plugs?

It is recommended to change spark plugs every 30,000 to 100,000 miles, depending on the type of spark plugs used and the driving conditions. However, if you notice any of the following symptoms, you may need to change your spark plugs sooner:
- Decreased fuel efficiency
