The DIS on your vehicle uses a waste spark system. This means each plug fires every full engine revolution. Furthermore, the way the coil pack and spark plugs are configured result in the spark plugs on one bank firing from the center electrode to the ground, and the spark plugs on the other bank firing from the ground electrode to the center electrode. This is exactly why you need to use double platinum spark plugs. Last edited on Sun Nov 26th, 2017 09:08 pm by CBB9M ____________________ -Bill 04 Ranger FX4 Level II, several mods |
