What happens if spark plugs are installed incorrectly?
Spark plugs that are gapped incorrectly can cause an engine to miss, or run erratically, especially during idle. The incorrect spark plug gaps can cause uneven firing of individual spark plugs and delay engine combustion; both of which can cause an engine to miss or idle erratically.
Why did my check engine light come on after I changed my spark plugs?
A blinking “check engine” light indicates a condition that could damage the catalytic converter. Engine misfires can throw unburnt gas into the exhaust and/or overheat the catalytic converter, so repeated misfires can trigger the flashing CEL. The possibilities are: The wrong model of spark plug for your car.
Can new spark plugs cause rough idle?
Failing Spark Plugs – The spark plugs create the spark that ignites the fuel in the engine. Faulty spark plugs, therefore, struggle to ignite the fuel, causing rough idle and difficulty starting.
Are NGK Spark Plugs pre gapped?
While most NGK spark plugs are pre-gapped, there are occasions when the gap requires adjustment. Care must be taken to avoid bending or breaking off the fine-wire electrodes. If the gap must be adjusted, use a tool that only moves the ground electrode and does not pry between or against the electrodes.
Will car run better with new spark plugs?

Why does my car vibrate in idle?
Motor mounts keep your engine attached to the car. Weak or broken mounts can’t hold the engine tight in the engine compartment and creates a vibration at idle. If the shaking subsides when the car is in Neutral, this could indicate the motor mounts are responsible for the vibrations.
How often should you change your spark plugs?
Many mechanics and manufacturers are beginning to set 80,000 miles as the new standard for the industry, but most mechanics still suggest changing them sooner. Most manufacturers advise that you can travel at least 80,000 miles before a change is required for the newest vehicles.
Why are my spark plugs not working properly?
If you don’t/haven’t experienced any of these symptoms with your car as of late, then you probably have good spark plugs.

This can cause the engine to hesitate, which will make it run at a rough idle.
Where does the Spark Go in a spark plug?
A literal spark jumps from the ground electrode to the center electrode on the tip of the spark plug. As this occurs over thousands of times per minute over the life of the electrode, the electrodes wear and the spark becomes less efficient.
Why are spark plugs important to your car?
