It takes a lot of heat to make the exhaust pipes get hot enough to glow red. It is a dangerous condition and can lead to a vehicle fire. A clogged catalytic converter or manifold could cause this, but ultimately the heat from the exhaust fumes is not exiting the system properly. Even a clogged tail pipe could cause this. A vandal might have stuck something in the end of the tail pipe.
It is running rough because it cannot push the exhaust out and therefore cannot take in enough air.
Regardless of the cause, have this inspected and the blockage/clog removed repaired and do not continue to drive the vehicle with this condition.

New plugs and wires?
Double check to make sure that you've got the routing and firing order right... if you have 2 switched, the car may still idle well but then pop and sputter on harder acceleration.
The next step would be to run some "Complete Fuel System Cleaner"... If that's the problem, you should see results within 20 miles or so.

I suggest to get the codes checked so you're not chasing a moving target. You'll need to look online - check out the Ranger/Explorer forums - or get the Factory Service Manual (FSM) to get the technical info you're requesting.
