Well I put in plugs as the ones in there were really worn. There was not much left of the plugs, 1 plug was wet so I moved the coil to a different plug and it was wet also after I started it and let it idle. So I put a new coil in and it still runs bad, like 4 or 5 cyls at idle. And it makes a clattering sound on the passenger bank of cyls. I think it is icky inside that valve cover. So I just stopped working on it for now.
