Worn Spark Plugs

You already know that spark plugs wear out. Well, “burn up” is more like it, because when a spark jumps the gap between two electrodes, it actually burns off (erodes) minute amounts of metal from each one. Over time, the gap grows to the point where the spark can no longer make the jump. That’s when you get misfires, poor gas mileage, lousy acceleration and, ultimately, the dreaded “Check Engine” light. Change your spark plugs yourself to maintain peak performance and high gas mileage. In most cases and with a few of the right tools, it’s a simple job.
