You should check your spark plugs periodically as they can give an indication as to how your engine is running. If the spark plug is fouled the engine wont work as efficiently as it's supposed to. A normally operating engine should result in a light brown discoloration, check your spark plugs against a reading chart like http://www.ngksparkplugs.com/techinfo/spark_plugs/faq/faqread2.asp If the spark plug is fouled or eroded, replace it. It's a simple job and spark plugs aren't too expensive.
