I've been searching and reading up and am thoroughly confused. I have a bad injector and if I'm going to replace the one I might as well do them all. I have no clue what to install. From what I gather it seems MOTORCRAFT #CM-4956 might be the one best suited. So many differences of opinion I don't know what to do. Maybe just replace the bad one with NOS and be done. Anyone know for sure what injector is best? My Jeep is stock.
