You know that you have a problem with your Mercedes ML320 spark plug wires if your engine is running really rough. You probably have fouled spark plugs and your engine is most likely misfiring as well. It is the job of the spark plug wires to deliver tens of thousands of electrical volts to the spark plugs.

These wires can get brittle and the core can crack as they get older. These flaws do not mean good news because the tens of thousands of volts are no longer being harnessed.

It is not always easy to tell from the looks of the outside wire’s surface whether or not these wires have aged too much. This is because many times the flaws are just under the wire’s surface.
