    I ASSUME YOU MEAN THE SPARK PLUG WIRES. GO TO AN AUTO PARTS STORE AND REQUEST A PICTURE OF FIRING ORDER. IT IS FREE. MAKE SURE YOU APPLY ELECTRIC GREASE TO THE SPARK PLUG WIRE ENDS

    The wires are not in properly. Here is a diagram on the firing pattern. http://autorepair.about.com/library/a/1h/bl764h.htm
