I just got this bronco from a neighbor of mine and it wasn't running and it had been sitting for quite a while and I got it running but now it runs really rough and shakes alot when it idles. I think that the spark plugs wires might be on wrong so if you could send me some diagram to show me how they go from plug to distributor for a 5.0 that would be great and also if you had any other ideas as to what it might be that would be great to. Thanks

Firing order is 1 5 4 2 6 3 7 8, in a counter-clockwise rotation
Cylinders are numbered 1 2 3 4 pass side and 5 6 7 8 drivers side
Number one should be marked on the cap. You might have a stuck injector, seen that before when something sits for a long time
