Master Tech · Real human

Good diag so far — since the miss didn't follow the coil or plug, you're down to injector, valvetrain, or compression on #4. On these 5.3s with AFM, cylinder 4 is one of the deactivation cylinders, and a collapsed AFM lifter is the classic cause of exactly this. Before throwing an injector at it: do a relative-compression test, then swap injector 4↔6 the same way you did the coil. If the miss still stays on 4 with good injector pulse, you're looking at that lifter…
