Edit: no codes except for the NSS bypass at this time.
Edit 2: Would a bad coil throw codes? It's so weird it only does it at low throttles, NEW TPS, NEW MAP, fuel pump must be good, has new fresh gas, new spark plugs, transmission shifts smoothly under acceleration, having the NSS bypassed shouldn't mess up anything like this right? It's only between 0-22ish% throttle.

RC if this is a vehicle that you want to chronicle the history you may want to check out some of the build threads, and see how some the guys over there started out with issues, and worked out the kinks and got a good build running.
Don't hesitate to use the search function too, once you get the hang of using search some of the routine questions can help you find the real hard stuff. I have found that searching this thread the tires and suspension thread and the walk thoughts forum have all been helpful.

I appreciate the kind words, but I learned a lot of what I know the same way. I have well over 10k hours of research and reading about Jeeps, suspension design, etc. I enjoy it, and I like learning. Anybody can get to where I am with patience and interest

Any other opinions on the impact wrench vs. breaker when attacking exhaust manifold bolts? Also, can anyone recommend anything else I should replace while the exhaust and intake are off? Replacing the CPS while I'm in there.
