84 380 SE firing order
 

My buddy just got a deal on it from a close friend of his. Been sitting up a while, 80k miles, Cherry condition. Running rough. Did plugs--wires, cap and rotor look good. Installed new fuel filter. Still rough. Thinking maybe condensation in fuel tank. Before i drain it, thought there's a possiblity someone crossed two plug wires. Looking for a drawing showing firing order in relation to distributor position. Anybody got one? If i can just come up with just the firing order, how do I tie that to plug wire connection point at the distributor?

if you put the engine at top dead center, remove the distributor cap rotor and the plastic cover if it is there, on the edge of the distributor you will see a line cut into the aluminum housing, the line represents cyl #1, the distributor turns clockwise and firing order is on the passenger side valve cover
