First off I would like to thank everybody who told me about the quarter trick. Fixed the missfire perfect. Truck runs better and idles smoother then it has since i bought it. Im not sure what injector it is but when you start it it runs fun. Give it some gas and its fine but as soon as you hit 1500 rpms you can hear one of the injectors start firing like 2 times between every stoke. Sounds almost like its firing to early or sticking open. It only happens when truck is under strain like pulling a hill or starting off from a dead stop. The RPMS can be anywhere on a downshift or coasting and it wont mess up at all. It does get a little better after it warms up but it still does it. When you push the truck hard to take off it sputters pretty good to and starts lurching the whole truck. So im wondering if maybe some dirt got into the injector or maybe it needs a new injector. I poured some K100 into the tank before this happened so what im thinking is that that broke up some buildup in one of the injectors but now its caught in there. Im hoping that if i drive it enough it will fix itself because I dont really want to tear those valve covers off again haha.

 

Do you have any mods? Mit try the Frx from Clay it helped mine big time. On another note maybe one of the injector wires are loose. Some guys by testing found out which injector is acting up and unplugged it then reconnectoed it and it was fine. Must take covers back off for that. Mine was a fuel knock so the Frx worked great.
