[QUOTE="Tiha, post: 1563368, member: 33189"] Ok finally started this project. Good news and more questions. First the obligatory cp4 check. All is well. I am disappointed in laptop and forscan. I can't do more that what I could with Bluetooth and phone. At least as far as troubleshooting information I need for this project. Expected to have an injector bypassing too much fuel. Nope. No return flow. Even engine running. None. Now I have cylinder contribution numbers. Truck warmed up. One set at idle, one set at 1500 rpm. Pic taken after about a minute so flow adjustments could stabilize. So what am I looking at? To me that says like 4 injectors but really #5 is all over the place.[ATTACH type="full"]187007[/ATTACH][ATTACH type="full"]187008[/ATTACH][ATTACH type="full"]187009[/ATTACH][ATTACH type="full"]187010[/ATTACH][ATTACH type="full"]187011[/ATTACH] [/QUOTE]
