When your facing the front of your bronco looking into engine compartment, on left hand side in
sequence is 1, 2, 3 front to back. on right hand side it's 4,5,6, front
to back. The distributor rotates clockwise. On the top of the distributor, is 1-4-2-5-3-6 starting at the little mark on the cap or TDC. Hope that helped.

You may have got the spark plug wires out of sequence.
Reseat the coil wire going to the center of the distributor cap
Check the spark plug wires at the distributor against the firing order as follows:
The spark plug firing order is 1 - 4 - 2 - 5 - 3 - 6
The distributor rotor turns CLOCKWISE The engine cylinders / spark plugs are numbered :
firewall 3 - 6 2 - 5 1 - 4 front
change one spark wire at a time on the distributor.buy new set of spark plugs wires remove them from box.match old wires with new wires to use the correct length to each cylinder.now if you need to change distributor cap.mark location distributor cap.number tag plug wires on the distributor cap so you can remove plug wires on distributor cap so you can replace cap and rotor and put wires back on the distributor cap in correct place.remember change one plug wire at a time so you wont get confuse.
check the spark plug wires are attached all the way till it snaps, pull each spark plugs, any black deposits on any plug means it isn't firing(faulty plug,or wire) last of all take off each injector wire and notice if there is a change in idle speed (plugged injector)
Did it spark well on all the plugs? Usually if you have no change in idle with two wires removed it needs a new set of spark plug wires. If it was cylinder 2 & 3 (side by side) then you should suspect a head gasket. Does the Bronco have multiple coils or a coil pack with multiple inputs? Are these two plugs hooked up to one coil?
Go through your spark plug wires and mark which plug it is on. Once you have done this then you can pull the wires off each spark plug. Once the plug wires are off take a spark plug socket and gently apply some pressure to loosen the spark plug. Once its loose you should be able to reach down and remove the plug by hand. Once you have the plug off grab your new plug. Make sure it has the correct gab setting for your engine size and then install the new plug. once you have the new plug in gently snug it down. Do this with the rest of your plugs. Once all your plugs are in place and snugged down then put your plug wires back on each plug (This is where the labeling comes in handy). It is also a good idea to get a good set of plug wires and just replace them while you are at it.
