How was it running with the old plugs and wires? How does it run when you reinstall the old plugs with the new wires? New plugs with the old wires?
Each coil fires alternatively. All cylinders on that coil get a spark. So the placement of leads must follow the firing order with every second cylinder in the firing sequence on the one coil. It will never be one bank on one coil and the other bank on another. The correct sequence is 1, 6, 7, 4 on one coil and 8, 5, 3, 2 on the other.i have a picture someone gave me to use passenger side bank is 2,4,6,8 . 2 closest to the radiator, and then drivers side 1,3,5,7 and on the coil pack bracket it has the number stamped on it,
