firing order 1-8-4-3-6-5-7-2

Any 2 plug wires reversed means 2 cylinders are not working. Not much to guess about. Sbm rotation is clockwise, #1 cylinder is drivers side front. 1,3,5,7 on drivers side, 2,4,6,8 passenger side, follow cap see where they go. Connection error is common on 5 and 7, they should cross each other from cap to plug.
