The website continues to explain that while carbon fouling can cause problems, if the spark plugs are cleaned,…
What causes a spark plug to go bad?
Inspect the spark plugs for damage to the insulator tip, boot and upper and lower insulators. Next, check the spark plugs for signs of fouling. A fouled spark plug occurs when the plug isn’t burning fuel normally, leaving damage to the plug which can cause the engine not to start.
It not only lowers vehicle gas mileage, but it can result in carbon fouling of the spark plugs. Unfortunately, it is impossible to prevent stop-and-go traffic conditions.
