5.3L Swap Hard Start and Sputtering

[Green67Stepper]

its been a while, but I wanted to update the thread. I figured out my hard start issue and I feel like an idiot. In short, I was having a issue with my ignition plug getting hot and melting the red and pink terminals. after replacing the plug I started tracking wiring and looking into what could be the cause. Finally I realized that when I wired up the motor, I never hooked up my 12v constant wires. I wired everything from my fuse/relays to 12v keyed power. So #1, I was pulling a ton off the one single keyed ignition wire and #2, my PCM never kept 12v constant. After running a new fused power wire from the battery for my PCM, it starts like a dream.

I am getting some sputtering/misfiring at high RPM/throttle, but I'm hoping its just the PCM re-learning everything and will clear up after getting some miles on it. I only drove 2-3 miles at most.
