Ok, Spark plugs are Auto Lite double platinum. Putting in ALL new coils (OEM) doesn't make sense. What would changing them all do? All of them checked out OK when I put them on an Ohms meter. I only replaced #1,2,3 because I am tired of have to take off the valve cover to get to the back side of the engine. What the next step if all the coils are replaced?
