Coil wires?

update...I adjusted the valves today, and I have two new pieces of information.
1. The spark end of the cylinder 4 spark plug has carbon all over it; it's black, while the other 3 are white.
2. More urgently, my car will no longer idle. When I have the clutch engaged or when it's in neutral, instead of leveling off at about 1000 rpm, it never levels off and eventually dies. I tried the idle relearn procedure I read (turn on car, hold at 3000, rpm until radiator fan turns on, let idle for 5 minutes), but when I try to let the car idle, it does the same thing--it dies.
Any thoughts would be appreciated.

Check the valve adjustment, after you turn the engine by hand so cylinder 4 is at TDC, all of the cylinder 4 rocker arms should be slack (not pressing on the valve stem). If that's OK, the problem is clearly inside the engine.

Ok, thanks. I adjusted all the valves this past weekend. Would it have been really obvious (even to a noob such as myself) if one of the rocker arms had been pressing on the valve stem? Because I don't want to go through taking the valve cover off again if I don't have to.
If it is determined that the problem is inside the engine, is the leak down test the place to start?
