Why would a 1997 Jeep Wrangler have a random cylinder misfire?

if it is not consistent IE not JUST the #4 cylinder, I would look at the distributor (button, rotor, etc), Ignition coil and the wire connecting them
Also, check the fuel injection, if there isn't enough fuel to drive the cylinder it just sits there (this is also a common reason people fail their e-checks). If the check engine light is on it should kick out a 200 code for the above problem.
If the code is just a 300, I would start checking the distributor and wires as said before, and of course make sure the plugs aren't cracked. If none of that helps, it is time to take the head off and check the seals around the offending cylinder. I hope that is helpful to you! -Katrina
