I friend brought me his 99 Jeep that idles rough and is very rough when acceleration. it seems to sputter and shake the vehicle when hes driving. It also has very poor power. i pulled the codes on his computer and a ignition coil problem came up. we replaced the coil rail as one of the coils physically looked damaged. but not change in performance. so i began pulling th injector wires to see which cylinder was missing. i tracked it down to cylinder 4 and thought maybe the injector was clogged or bad. i replaced the injector with still no luck didnt change a thing. he has tried adding fuel system cleaners and changing filters with no succes. i have pinpointed which cylinder is missing but cannot figure out why, i dont know much about jeeps so i'm sortof at a loss i hope you can help point me in the right direction
