I recently was having problems with my 07 Jeep Wrangler it wasn't running smoothly and the engine was stuttering, I can alot of injector cleaner through it but the problem persistent. I changed the oil, the plug wire, the plug control module, and the plugs. But still one of my cylinders isn't firing. Whenever I unplug it from the module there is no difference in how it is running, but when I unplug a different wire it shocks the shit out of me. What could it be that keeps this one cylinder from firing? Please help /o/

If it's not firing, then check your OBD2 codes.
