From what you've described, the likely issue may be related to timing during initialization. After completing the driving portion, you should ideally: 1. Keep the vehicle running after the drive cycle is done. 2. Shift into Park and make sure the vehicle is stationary. 3. Wait a moment before...

How many times have you tried this process with it failing?

Here is a few things you might want to check: Idle Air Control (IAC) Valve: If this valve is dirty or malfunctioning, it can cause stalling at idle. Cleaning or replacing it could help. Fuel System: Check the fuel filter and make sure your fuel pump is working properly. A weak fuel pump could...

Check Rubicon Express's official website or reach out to their customer service for the most accurate part numbers. They might have specific ball joint part numbers listed in the installation or repair manuals.

Your ideal tire pressure is going to be closer to 26-28 psi, I can almost guarantee it. I would take the wheels in and have them balanced. There's a good chance a weight fell off of them.

Many folks have successfully programmed the WIN module using the J-Scan app, provided they have the right firmware version and accessories set up properly. However, the dealer route is often recommended for those who may not feel confident or who have the peace of mind knowing everything is done...

Scan it with a code reader and tell us what codes it's throwing.

Yep, reach Mark through his website. Either that or give him a call (number is on his website too). I know Mark well, that's why I'm speaking for him ;)

From what you've mentioned, it seems like you did a thorough job checking the heater resistance and continuity. Your O2 sensors' resistance values are within the expected range, and the continuity readings on the control wire also look good. However, the low voltage readings at the PCM are...

The P0031 and P0037 codes indicate a problem with the O2 sensor heater control circuit. To answer your question about the heater control lines: generally, you should see around 12 volts on the heater control circuit when the engine is running. If you're noticing significant voltage drops or...

This one actually looks really good, I agree!

Indeed, the first place to look IMHO is always the wiring.

Pretty sure that's the oil pressure switch / sensor.

It sounds like you're on the right track with your diagnosis, and the fact that the codes cleared temporarily is a good indication that there might be a communication issue, likely related to the TIPM as you speculated. The U0141 code indicates that there is a loss of communication with the PCM...
