I had my valve cover gasket replaced and the truck sat for two weeks before I finally started it and now has cylinder 1 misfire and runs rough.. I replaced coil and plug and still same code cyl 1 misfire. I pulled coil and plug and started the truck with the plug and coil connected outside of the valve cover and the spark plug actually has a constant spark but i could only see it in the dark..problem is I don't have any idea how bright it's supposed to spark!?? I need help, I was just trying to fix the oil leak! Ran great before
Can I rule out the coil connector because I actually have some spark?
