Last week my 96 XJ started stumbling really bad and would stall shortly after. Threw a P1391 code and I figured it wasn't the crank sensor because it started up every time no issue so I replaced the distributor, which the new one included the cam sensor. It runs great now, smoothest it's run since I got it but it still throws a P1391 code after driving it for 20-30 minutes. What else should I look into? All the wiring that I saw looks good and I made sure the timing was right. Any help is greatly appreciated!

 

I'm having a similar problem, but I don't see any reply to the initial inquiry. Is there some different process for accessing older (Jan 2020) info?

 

just saw the new thread, i posted there
