Re: 2000 XJ won't hold idle...sometimes
That is just the computer trying to learn to idle again.
I don't know if this works for Chryslers, but it works for the older
GM's to reset it fast. You drive for 5 miles at less than 30 mph, then
pull over and shut it down. Start it back up and drive another 5 miles
under 30 mph and shut it down. Then start it up and floor it up over 30
and drive normal from there on.
This will make an older GM computer purr at idle again.

Re: 2000 XJ won't hold idle...sometimes
Wonder if the battery is still a bit low and the pcm is widening the
injection pulses to compensate?
