Need an oracle! Low speed miss on cylinder #1 only. - ZR-1 Net Registry Forums

I am checking the weak spark by pulling the plug wires and letting it arch to the valve cover bolts. That is how I know the spark is weak on cylinder #1. All other cylinders have great spark! Also it is intermittent so I know it is not compression. It maybe a wire, but I don't know where. I am going to check the grounds and the four wire connector to the coil plate. These is a weird one.
