Trying to get it mostly right the first time: A 5.9 Magnum and 46RE swapped, Tummy Tucked Daily Driven Jeep TJ

I finally carved out some time to update this thread.

Picking up from where we left off, I decided to take a weekend to get the Jeep back up and running. The short answer is that it's fixed, though I'm not entirely sure what the problem was. I pulled the intake off and re-sealed it (in hindsight that was mostly a waste of time), cleaned and reinstalled the original IAC and cleaned the throttle body and that fixed the issue.

The test drive for the Jeep was a few trips to work and then a 300 mile round trip to Auburn and though the stalling issue was resolved, it developed a bad misfire that I suspected was due to poor plug wire routing on my end. A few poser pictures from our Auburn trip:

The misfire got so bad that the Jeep was practically undrivable so this was the next issue to dive into. These engines are known to have an issue with spark knock caused from improper spark plug routing (there's actually a TSB for it), so wire routing was the first thing I confirmed correct. Next I started pulling plug wires one a time and checking for resistance. Sure enough one of my brand new plug wires had gone bad (or I'd broken it) so I threw on an old wire and it's been running like a top since.

Enter January of 2024 and the cold temperatures exceeded my motivation to work outside so I moved to working on things that fit inside my shop. I ran to the farm and picked up the 8.8 I purchased a while back and stripped it, welded the center section to the tubes and primed and tacked the Barnes 4wd truss to prep for the axle swap. I'm shooting to swap the axle out this summer once I've sold a few jet skis to replenish my project fund.

No real updates on the TJ as it's been serving part time DD. Total miles on the swap to date is 5,779. I've been collecting parts for the next round of work, including 3.5" JKS Dual Rate Springs, a set of JL Fox shocks and am planning out the cooling system changes / upgrades / modifications as well.

I do have an update on a Jeep related bucket list thing that I've wanted to do for going on 20 years.

I first subscribed to Peterson's 4 Whell and Off Road in August of 2003 which featured UA coverage in the southeast at some of my local parts and I still have that issue to this day. Frankly, I credit that subscription to 4WOR to much of my passion for the off road hobby. The issue with Easter Jeep Safari in 2004 would have been my first exposure to Moab and it has been a bucket list trip arguably ever since.

When family vacation was planned for Park City, Utah this year I knew this was a prime opportunity to make that happen. Side bar – turns out I'll be driving from AL to Moab in October to ride co-pilot with a RZR crew. After some research, the plan was to leave Park City one morning, hit Arches National Park around lunch and then do a ride along Jeep tour with Twisted Jeeps. The next day we'd hit Canyonlands National Park and head back to Park City.
I pulled some strings at the airport and changed our rental car to a '23 Rubicon 4xE. I love my TJ, but man is the JL plush! The trip went exactly according to plan (shocker) and Twisted Jeeps was fantastic to do business with. Our guide, Jeeper Jeff, was a super cool dude and let me drive a few obstacles he technically wasn't allowed to. Here are a few pictures from the trip:

That's great you got to make that trip out to Utah.
For me it was the Easter Jeep Safari VHS tapes I had in the late 90's.
Man that seemed like a cool area.
My first time out there was 2 Summers ago with Myrick and Jamin.
I loved every bit of it. The heat was worth the views for sure.
