  • thank you mr. shiftright that should help, and yes i am using the right oil 20 w 50 not sure what an OEM filter is though I did use and after market filter from the local parts store not sure its the filter though had the same problem before and after the oil change. now not sure if i should replace the old sending unit to see if that cures the problem or go ahead and istall an after market oil pressure guage. seems to be alot of problems with jag. gauges not the only one here that seems to have that problem. anyway thank you for your info. nice to have folks who care.

    Well that sending unit is over $100, so you might not want to be guessing. At the very least, I'd be more inclined to pay a mechanic $100 to screw in an accurate mechanical gauge and tell you what's what for SURE. The aftermarket gauges aren't very attractive, after all, hanging like that under your dash.

    Depending on how good the parts stores are in your area you might be able to borrow/rent/lease a mechanical gauge from them.

    I own a 2001 Jaguar XJR. Every once in a while I have the same problem. I take it to my dealership and they find that the gear-shift cable requires adjustment. I'm not a certified mechanic, but I understand cars quite well, and this makes sense for my particular problem. It's never needed replacement, just a slight tweak here and there, and it goes away for a while. This has happened three times in four. I hope this helps.

    My 2001 XJR, 97kmi, is overheating. I can stay at idle all day long with no problem, but as soon as I take it around the neigborhood for five minutes the needle hits the red. I don't have to exceed 30mph at 3k rpm to duplicate the malfunction. Any ideas?
  • MrShift@EdmundsMrShift@Edmunds Posts: 43,700
    I would guess a coolant circulation problem rather than an air circulation problem, so it's not the cooling fans, etc but rather a restriction in flow or inadequate circulation. So, clogged radiator, bad thermostat, bad water pump or perhaps a leaking head gasket as the worst case scenario.

    the radiator is low in the vehile .they are prone to hitting parking stops and if you drove afterwards you might not notice the engine siezing.do you have insurance?and mbz is not jaguar...

    Have been very fortunate in never having had problemswith my beautiful Jag. However this weekend it just slowly died at a traffic light. Maneged to limp the 300 yds home. When I power up the revs go to 2k revs in park with no accelerator use, then slowly..on its own drops until it stalls. It will start again but same process, changed the fuel filter figuring fuel problem [the fuel coming from inlet side of filter was extremly brown/rusty] I also noticed that on occassion the pedal needs a tap or two to take from tickover, thought this may be throttle linkage etc etc sticking but wouldnt explain the stalling. I have a fear its electrical..as most posts on hear appear so. Once in ablue moon the 'trac-off' comes on but not while driving, a switch off and back on solves this.
    Have just completed 100k miles so not too many for this year.
  • well if it's an 85 then the chevy engine scores you major reliability points
  • Hey I am looking at a 99 Jag XJR now, and am ready to go but some of the bad experiences some folks have had have me just slightly nervous. Mostly with the 03, 04, but mostly positive from the slightly older ones. What have your experiences been with reliability? That is my main concern. Jags sure depriciate fast, do you happen to know the reason behind that?
  • have ask questions before and always got help. hoping for more help now,I have a 1991 xjs on the trunk is an emblem that says Collections Classic. Never thought anything of till I was in a classic dealers show room and they had 1 and claimed it was 1 of only 273. There were a few differances between this one and mine. first this one had a jag. hood ornament mine has a gold medallion with a jaguar head on it. His console was all one color that matched the interior with a wood handle on the shifter. Mine the console has a wood top that matches the dash with a leather handle on the shifter. They both have the collections classic emblem on the trunk. Can someone help me to find out if i have 1 of 273 ? Are there are any sure way to tell if it is really 1 of 273..thank you for any help you may have
  • still needing answers is there a way to tell for sure if my jag. xjs is 1 of 273 it does have the emblem on the trunk saying classic collection. other than that how do you tell? Please give me some help..thank you
  • Yes the Classic Collection was a special trim package you could order. Jaguar did a number of these over the years as marketing schemes-- another one was called Collection Rouge. Classic Collection cars featured special piping on the seats, leather wrapped gearshift and elm veneer wood trim, and I think some selected paint colors.

    I would caution you though that trim packages don't often translate into any extra value, since they don't represent any major mechanical or body changes of any kind, just cosmetics. Also, the reason they are rare is because not many people ordered them.

    so you may indeed have one of 273 but it may not matter as far as value is concerned. Still it's nice to have something a little different and it might represent a small bump in value if you want to sell it--maybe 5% or so.
  • thank you Mr. shiftright.Your information was very helpful I do indeed have the model you spoke of. It is a beautiful bright red and has all the features you said. I have seen 2 of these on ebay they both were above the $12,000.00 price tag. Mine is very very nice but not perfect it has 75,000 miles on it. If anyone is interested it is forsale and less money.. contact me i have photos for you to see again thanks for the info.
  • Well you can't sell or advertise a car in these forums but we wish you luck. Asking prices are the eBayers exercising their First Amendment Rights, but $12K is a mighty strong price for such a car. If someone offered you anything from $8500 on up in this economy, I'd sure consider taking it.

    I had the same thing happen but the oppisite the dealer replaced the throttle body then it happened again and they supposedly called in and expert and they replaced it again then told me that the computer was no good. I and a good friend who works on cars started looking and found the plug on the throttle body was not making good contact we tie wrapped it up and it worked good for 6 months now I am looking for another plug or harness.
    Good Luck

    Does anyone know were I can buy the wiring harness for the throttle body for a 2001 xj8 ?

    Thank You
  • stanchostancho Posts: 1
    I have a 2001 xj8. I had to replace 2 throttle bodies and the problem was still there. failsafe/ no asc/no trac.
    someone posted on one of the forums that his connecting wires where loose on the throttle. I have cleaned all connectors with the connector cleaning spray - from pepboys and never had any problems again. the throttles cost me more han 2,000 and it was a simple connector issue to the sensors on the throttle.
  • lzolidislzolidis Posts: 6
    Thanks for your advice on the throttle connector. I haven't had the throttle body issue come up again since the second replacement in 2007, but shortly after that procedure I began to get smoke from the exhaust pipe on a "cold" start to the car (i.e. after it was sitting for awhile). The dealer took the entire engine apart and found sludge from the prior leaseholder (Jaguar owned before I bought it). They claimed they got all the sludge, but then it happened again. After the second very expensive clean-out, where they claimed to take the engine apart "even further" than the supposedly complete first attempt, I changed dealers to one nearly an hour's drive from my house. I am much happier with the new place. The 10,000 mile checks are more thorough and done MUCH faster than the old, awful place, and customer service is excellent. My advice in the DFW area: use Overseas Motors for service, not Autobahn.
