Hi,
I picked up a 97 xj last weekend with the previous owner saying it had no spark and he had put in a new coil and CPS with no luck.
The passenger engine mount had broken off and the engine was resting on the distributor which it bent and seized so the distributor gear broke.
I pulled what I could find of the gear out of the oil pan, put a new distributor assembly in, and the engine fired up and after reving idled decently. Tried driving and once it heated up it ran badly, wouldn't idle and anywhere above 2k rpm it's as if it's hitting a rev limiter.
Also pulled the codes p1391 and p0320 so I thought it was the new cps or cam sensor in the distributor. I swapped both back to the originals and the issue persists, still giving those codes. I've measured the resistance from battery ground to the group terminals of both sensors and it's under 1 ohm so I have no idea what it could be. The battery is brand new.
Hoping anyone might have an idea of where to start to figure out whats wrong with it? I also started it this morning before swapping the sensors and it ran nicely but it was cold
