     Use the spark plug wire boot tool to make removing each wire easier. If you do not have the tool, carefully unhook the old wire with your hands. Remove and replace one spark plug at a time. Carefully unhook each spark plug from the valve cover and trace the plug back to the terminal. Replace the spark plug wire according to its number.

     Go over both connections for each spark plug wire to make sure they are properly connected. Spark plug wires have a small clip inside the boot, which should make a "pop" when properly attached.

     Start the engine and make sure it is not misfiring. If the engine is still misfiring, double-check your connections. If the connections are good, you may have a faulty spark plug rather than a faulty spark plug wire.
