Master: Your final 2 are really 2 different cars. The XJ6 is the old pre-Ford Jaguar design, a fine Cat, but complete with the Lucas electronics nightmares and prone to dropping a quart of assorted fluids nightly from various places under the car. Not a low maintenance car, but a thrill to drive, to be sure - when you have her running.
The XJ-8 is the new Ford owned Jaguar design XJ, which is not to say the car is any less Jaguar at all, but Ford had made some serious quality improvements in the company by then, and the new design of the XJ-8 proved to be much more reliable then the old XJ-6 was. Nobody liked it less that I've spoken too. The electronic nightmares were nearly gone. I think it's worth the extra money, myself.

The 99 probably has a Nikasil engine in it. I would be weary to so extent as Jaguar has replaced many of these under warranty. Apparently, high sulfur content fuel with short city driving affected the Nikasil liners in the engine. Have a blow by test done on it to see where it is at.

A reporter with a national newspaper would like to speak with professional women who for the first time are buying a fun car or truck they have been longing to own but were not able to buy before because it wasn’t practical. This vehicle purchase is a splurge. The reporter would like to speak with first time buyers of full-size trucks, convertibles, Miatas, Porsches or Jaguars. If you fit what the reporter is looking for, please email a brief description with contact information to Kirsten Holguin at kholguinedmunds.com as soon as possible.

I have been thinking about the stalling you asked about.
I would suggest a couple of things.
First, I agree with another post that the fuel pump maybe should be replaced as it could be defective or failing and perhaps is showing this symptom when it is "stressed" (sounds familiar to the human condition - ha !) by temperature or flow volume.
Second, I would replace the fuel filter, perhaps, once or twice. A vehicle of this age, if not driven on a frequent basis, could have developed sludge or contamination in the fuel system (picked up some bad gas). After a while, the filter will pull up enough sludge to foul the engine. The fuel system had to be cleaned.
Third, check to the "throttle body".
Fourth, again if not driven over a period of time you might have gas that has eroded to a gum - "shellac". If a vehicle is stored for sometime, even over the winter, it is wise to add "Stabil" to the gas to prevent this condition. A cure is to drain and purge the fuel system and clean the carberator and injectors.
I hope some of these "thoughts" are helpful.
Let me know what turns up.....I am curious.

Let me "throw in some thoughts".
I firmly believe, based on experience, that the late model XJ's >1996-1997- are the very best of the series. They represent the end point in the perfection of the in line 6 which is one of the best, if not the best, engines that Jaguar has built....a true workhorse, long lasting and very reliable.
On the other hand, the "first editions (1998-99 maybe 2000)" of the XJ8's seem to have had some annoying "new edition launch" problems.
Now about Lucus. They have been panned over the years and the butt of many jokes, some of which were "well deserved". But, they have been around for sometime and get blamed for some frustrating problems which as plagued other manufactures under some very good marques.
But, I must say that my expierence over the years has been that Lucus electric in these late models (1996-1997) XJ 6's has been quite good as they perfected ie. -"worked out the bugs" - over the years.
Bottom line is that if I were buying, I would look for and not hesitate buying a "pristine" XJ6 (1996-1997) which evidence some positive Ford influence.
I really do love the "personality" of the XJ6 !
If you like greater and greater Ford influence and the "newer engineering", I would look for a XJ8 in as late a model year as you can afford, preferably the last years before the new aluminium model (2004).
Hope, these personal - "Jag Lover" - thoughts this give you some "good food for thought".
These are really great motorcars with special personalities and demand well deserved TLC.

I was wondering, by your "jag lover" (in quotes) comment, do you frequent that website?

I did put "jag lover" in quotes.
You made a sharp observation.
Interesting site for us "Jag Lovers" !

A questions came up the other day among us Jag owners.
The discussion centered on the following:
Is it wise to switch to a synthetic in older XJ 6 and XJ8 engines as the synthetics are touted as having longer life and better lubrication qualities ?
There were conflicting opinions on this nor did anyone know if there an "official" Jaguar position?
Anyone have an expert opinion / experience ?
#2145 of 2801 Inquiring about "Brentwood Bill"
Jun 11, 2005 (6:16 am)
Over the years one of our best experts on XJ Jags was "Bretwood Bill"
I am wondering if he is still around "the net".
If so, I hope he will log on and give us his sage advice.
