So ... after getting gears & axles done, moving on to the CEL.
Plugged in my reader and it popped out the 4 codes above. Looking through some websites, one solution for an XJ was proposed to replace the associated fuse by the battery because it might've been shorted by one or more sensors getting melted by the exhaust.
Have a few days of high temps around 10 degrees, so I won't be working on it until it warms up a bit and the garage heaters won't be struggling. Hoping to see some others' thoughts and/or if the fuse fix works.
Obvious solution is to install a complete new system from the manifold back and use the NTK sensors which I most likely will do during the spring.
