that sounds like maybe a couple of wires got crossed recheck the wire digram and then check the wires, next check the cap and rotor it might be cracked start with these things
The firing order and spark plug wiring layout is depicted in over-the-counter repair manuals like the Haynes for '87-93 Ford Mustangs. If you can't spend the ~$20 on one of those (available at Pep Boys, Autozone, eBay, Amazon, etc) you should be able to check one out from your local library.
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?
You may have cross a couple of spark plug leads. Check your firing order and then trace the spark plug wires back from the cap. You may also have the timing off. If you can check the timing with a light, you may need to adjust that as well.
