Gave up on looking for the splice that was supposed to be in its ground circuit, and backtracked from the connector on the O2 sensor. Should have started there in the first place instead of trying to work from the ground, backwards. There was no apparent damage on the outside of the loom cover...

Well, I finally found a little time to dig into it deeper. It set a P0135 code (I'm sure that's the one it set last winter.) so I started with the upstream O2 heater circuit. Rechecked the fuse for the heaters and it was good, with 14V on both sides when running. 14V at the O2 sensor connector...

I had a fairly lengthy reply that somehow never made it to the thread. Anyway, thanks for the input. The cap/rotor/coil/wires were all replaced when I bought the xj about 5 years ago. Strong white spark and the parts all look good. Sensor heater fuse is good, and the wiring shows no...

I got the vehicle about 6 years ago. At that time I replaced the coil, cap, wires, plugs. So that's all the fresher the tuneup parts are. I replaced the fuel pump module about 4 months ago (Bosch) due to hard starts (check valve). Replacing the pump didn't seem to have any affect good or bad on...

98 XJ with 4.0L. This problem started out as occasional and only at higher temps, but has increased in frequency over the last year or so to where it now happens every time. It will start fine in any temperature, but when warm (mid 80s or higher ambient, or if engine is still warm from...

8.25 is supposed to be released early next year per an email from Ox. An Eaton would be nice, but we should have another option before too long.
