[QUOTE="WestCoastDan, post: 464061, member: 23120"] Ok, here’s where I’m at now. First off, ZERO complaints w/ Wrangler Fix. Cruising along on the freeway and the lightning bolt & CEL illuminated; pulled to shoulder and checked codes. All of the previous codes were again present. Cleared the codes and headed towards the next exit. Codes returned at the stop light so I headed to the nearest parking lot to diagnose. Cleared codes and checked battery connections as well as the plugs that connect to the ECU, then pointed it towards home. Made it home w/o any issues. Literally the only thing I did was jiggle the battery terminals and the 2 ECU plugs to ensure they were tight. This makes me think the ECU was actually NOT the root cause, and I’m growing very suspicious of the wire harness that connects to the ECU. I have the weekend to either dig into it more, or get started on the hunt for a new vehicle. [/QUOTE]
