low idle issue
Ok so my xj idles real low and the lights flicker at the same pace... what would cause this? I seen some threads and they said the battery but my battery and alternator are both new... does it sound like a vacuum leak maybe?.. someone else said distributor?

While you are at the parts store buying things to throw at it, ask the guy to throw a tester on it and see what the alt and battery is running. Have them test the whole charging and starting system. I have seen alternators go bad quickly and if you installed a remanufactured one its not out of the question. There are a list of things you could do but its all in vain if you dont start simple and have the system tested.

I already seafoamed her... ill go and have the alternator and battery tested later... I started having this problem after I changed my valve cover so I'm assuming it could he s vacum line I might have missed but everything looks hooked up correctly... if anyone could post a pic of the top of their 4.0 engine bay I would appreciate it... I just want to make sure everything is hooked up

Maybe an o2 sensor but that should not cause flickering lights and low idle. At least I wouldnt think so that is why I still think your Alt is going out.
