Engine knock
After chasing a bunch of issues, I put remanufactured injectors, new plugs and coils and a programmed PCM from flag ship.
Well one of he reman injectors was so poor it filled the intake runner with pressurized fuel, and after three runs of having to flush the cylinder, I finally swapped the injector for one of the old ones, and now the truck has a knock in that cylinder. It's an obvious tip-tap coming from the cylinder. I only ran the truck for 20 seconds or so. Any advice on where to go from here? It ran great for those 20 seconds but after confirming yes this is indeed a knock, I shut it down.
