running core 4x4 control arms with JJ’s. No issues.

Followed many peoples advice and welded the 8.8 tubes to the housing. Used nickel 55 rods and a lot of preheat. Was far more difficult than I anticipated. The nickel rods are extremely soft. Not what I was used to. made 3 initial passes and then cleaned up some messy spots with a TIG torch...

All together I paid $300 for both axles. Found them locally on craigslist and offer up. Over the past week I’ve stripped them down and completely gutted the 8.8.

Gonna try to keep a “build progress” thread going for my 8.8 and HP30 build. I’d say this the first major project I’ve tackled for my TJ. I’m a backyard weekend warrior type mechanic and I’m learning as I go. Always looking for advice so please feel free to post opinions and thoughts. I’ve used...

That actually is a big help. You are reminding me that I need to wait a few fill ups before I can truly see if I’ve made any progress. I appreciate the post. 🤙🏽

I live in SoCal, although I think it’s freezing out it’s only about 45 at the lowest.

Temp reads 187°F at the thermostat with an IR thermometer

I’ll take a reading later today. Do you think I still have a temperature issue?

So I was able to get my hands on a buddies ODB2 ready. It was pretty low tech so it wasn’t able to read current engine data but I believe I was able to get the information I needed. The code reader takes a “snapshot” of current engine conditions when a CEL is tripped. So I let the jeep warm up...

I appreciate the info for sure. This is the first time I’ve had to troubleshoot a problem like this. Obviously the jeep isn’t running right but there’s no codes and no major problems. It’s just a little “off”. I’m trying to do this as intelligently as possible without throwing money at it. Do...

Thanks for the input. I’ll look into it. My floors do get damn hot but I don’t have carpet so it’s hard to tell if it’s getting hotter. How many miles did you have when the cat went? Im rolling 178k. edit: I have definitely noticed a decline in power/torque when the original problem popped up...

I don’t but I can probably get it tested tomorrow. I’ve been using a IR thermometer but it’s hard to get an accurate reading.

Replaced the temp sender/sensor with a Delphi. Symptoms remain. Replaced the thermostat with a super stant. Symptoms remain. Still running a little cool.

Go got one of those coming in as well. Appreciate the help. I’ll post up what I find.

Crazy. I put in a stant 45359. I have another coming in this week. I’ll give it a shot. Have you seen these stants DOA like this?

Thanks for the reply. I’ve read that quite a few guys see the needle ride right at 210. I guess if I’m running low, especially below 180, the computer will run the engine rich. Have you had any issues with poor MPG?

Could I be running a bit cold? This was at idle after a 30 min drive. 45°F Outside. Heater on low. The top of the radiator measured 167°F with an infrared thermometer.

Thanks jerry. Your posts on this forum have helped me out for years. Is there separate “computer” and “gauge” sensors? I’ve read that different year TJs have 1 or 2 temp sensors. The gauge appears to be working properly. I actually did a coolant / heater core flush along with a new thermostat...

Successfully solved a low RPM acceleration sputter a few weeks ago but now I’ve been getting significantly lower gas mileage. Normal MPG is about 15-16 monitored for years, but it has dropped to 13 tops. here’s a timeline of the issues and troubleshooting: while stuck in a traffic jam I...

Similar problem happened to me the other day. Driving home form work in a bit of a traffic jam noticed sputtering at low RPM and much reduced power. Also had a rich exhaust smell. Changed out the upstream O2 with an NTK 23151. Drove around today and the problem still exists. Decided to unplug...
