Where the coils fit down on the plugs they have holes for a locating screw,and the other one is brass or bronze.Is the brass one a ground?If so that might be my trouble all along.I removed coil cover and painted that area,and the brass screws got painted
OK all: the guide pins,and brass screws are a ground for the coils.I got paint on mine,it should clear my no full throttle problem when I clean them today
