Spark Plug Maintenance: Replacement and Performance Tips for GMC Owners

Spark plug maintenance is a routine task that helps a vehicle perform well. Wilson GMC Stillwater in Stillwater, OK offers spark plug inspection and replacement for all drivers. Healthy spark plugs keep an engine running in a smooth and reliable way. Contact the service team to learn more about the condition of your vehicle.

Function of Spark Plugs

Spark plugs create a spark to start the fuel and air mixture in the engine cylinders. This action provides the power that turns the wheels of the car. When the parts are in good condition, the fuel burns at the correct time. This leads to steady speed and better fuel use. Worn plugs make the engine work harder and can cause the vehicle to shake.

Signs of Spark Plug Wear

A driver may notice signs that spark plugs need attention. One sign is a rough idle when the GMC is stopped. Engine misfires can also happen during speed changes. This feels like the car is hesitating when the driver uses the gas pedal. A decrease in fuel mileage is another common symptom. A check engine light may appear on the touch screen in some models. If the light is on, a technician should check the vehicle.

Impact on Engine Performance

Ignoring maintenance can lead to other engine problems. Worn plugs can cause unburned fuel to enter the exhaust system. This can damage the catalytic converter. Repairing a catalytic converter is a more complex task than replacing spark plugs. Misfiring cylinders also put stress on other parts. This increases the amount of fuel used.

Maintenance Tips for GMC Vehicles

Drivers should follow the service schedule in the owner manual. When the plugs are changed, the technician should also look at the ignition coils and wires. These parts work with the spark plugs to start the engine. Always use parts that match the specifications of the GMC. Using the wrong plug type can cause performance issues.
