I have a bad coil on the #4 cylinder, what harm to the engin would I do if I drove the car about fifty miles?

Actually, it SHOULDN'T hurt too much other than bad fuel mileage, lack of power, and a miss. Hoever, remember the fuel will not get burned in that cylender that can make its way to the catylatic converter and into the oil thinning it. If you can avoid it, I would, but you should be okay. Please understand I can't guarantee it.

Let me know if you have other questions. Also, they are easy to replace. I would recommend replacing it. If you need directions, let me know.

This is basic. Just unbolt the coil pack, disconnect the wiring harness remove the old coil and reverse the order to replace it.
