I have a 04 wrangler. cant figure out way is it running so bad. I have changed plugs, tps, camshaft position sensor, crankshaft position sensor and coil and it still is missing and running poorly, I bought a scanner and it says that I have a misfire on # 4 and open circuit on injector #4 and TPS, I replace the #4 injector and the TPS and it still is the same with the same codes. Dont know what to do next. Any help would be muchly appreciated. Thanks

If it is still giving you an open circuit code then the connectors and wiring need to be checked.
