Also check the ignition coil not sending any spark to one cylinder.Check all the ignition cylinders if any of the cylinder burnt out it will spit and sputter also check the coil pack.you have replaced the spark plugs But check the voltage to spark plugs.the spark plugs gets power to spark from coil pack.If coil pack is burnt then it will not give required power to spark and due to this vehicle will spit /sputter.
