[xj-s] First Post - 1993 XJS Purchased in Kuwait

Hi All,

Wanted to introduce myself. My name is Mike. I live and work
in Kuwait (for 18 years now). I just sold my 1992 Ferrari
348 and got cash and a 1993 Jag XJ-S. It is white (original
paint all around) with red interior.

I LOVE this car!

It appears to be original, unmolested, and just needs some
TLC. I’ve had it two weeks now, and have done the following:

Changed all the fluids
Changed the filter and gaskets for the transmission to stop
some seepage
Repaired a leaky metal radiator overflow tank
Replaced all the water and vacuum hoses (at least all that I
could see)
Repaired numerous wires with cracked insulation in the
engine compartment
Covered all the wiring in the engine compartment with
additional insulation
Cleaned and flushed the radiator
Replaced a number of ‘Chinese’ brake and light bulbs with
Osram (German) bulbs
Replaced the two fog lights under the grill because of
cracked glass
Replaced the two support struts under the trunk lid (MY GOD
that’s heavy!)
Repaired a leaky Washer Fluid tank
Replaced the Windshield Wipers
Vacuumed, Charged and Oiled the A/C Compressor
Had all the tires replaced, balanced, and a 4-wheel
alignment done
Repaired the automatic radio antenna which wasn’t automatic
anymore
Replaced the four ‘‘V Bushings’’ on the rear axle and the
Trailing Arm bushings (I’m not sure there was any rubber
left on any of them)
Replaced the four original Phillips speakers with exact fit
Sony units (Sounds Great)

I still have to try and find a right front Headlight lens
(broken from apparently a rock) (not holding out a lot of
hope for that, but looking locally first)

Also need to sort out the Throttle Position Sensor… ($600
locally). Occasionally, the car won’t start unless you
jiggle the TPS wires slightly, then it starts like a champ.

The car is in very good condition, and I’m working to get it
right… I look forward to participating in this forum with
everyone. I was very active on Ferrarichat.com when I had
the 348, and enjoyed the sense of community.

I think, hope anyway, I’ll find the same here.–

Welcome Mike:

You have done an amazing amount of work, especially in such a short
time. Would you like to stop by my place?

If you search the archives, there was a recent post about a Mustang
(Ford) TPS fitting with a little work.

Good luck and lots of fun.

Hi Mike,

Welcome to the list/forum! Is your 93 a V-12 or 6-cyl? Most 93 models
were 6-cyl, but depending upon market, some titled as 93 could be the
6.0L V-12.

I would suggest removing the TPS and testing the wires for
continuity/short, particularly the 3 for the EFI ECU circuit (if you
also have 3 more wires for the trans ECU). You may have to
manipulate/jiggle them to duplicate the fault. Most likely your
problem is from broken wire insulation (particularly if you have the
V-12 where it gets very hot in the valley), or corrision in the
connector. Repairing the wiring and/or cleaning the connector may well
fix the problem.

I wanted to thank everyone who responded… I just realized you can
respond privately on this forum… (I couldn’t understand why, when
I logged on, there were no replies)…

A number of people asked what the engine and configuration were…
It is a 1993 XJ-S coupe, 5.3 V12 with a GM400 auto transmission. As
I mentioned (I think) it is Glacier White, with red leather
interior and red carpets. The post covers and headliner are grey.

George, thanks for the advice on the TPS… it is the red ‘‘better’’
TPS. I’ve removed it once, and didn’t see how I could repair
anything… I’ll take a look at the wires that connect to it and
see if there’s anything I can fix in that respect. It would not be
a good thing to spend a lot of money on a new, or used one, and it
not fix the problem.

I’ve only had the starting problem once in the last week of full-
time driving…

Oh, I took the advice in the book by Kirby Palm, and gave it a good
old fashioned ‘‘Italian Tune-Up’’ this afternoon… twice!

The first time, I was convinced that I’d blown a head gasket…but
after about 10 seconds the grey smoke went away, and I ran out of
road…so I went back to normal driving…

Then an hour later, did it again… NO SMOKE! NADA!

Now, if I can figure out why the idle is a little rough… in
drive, at a stop light, it idles at about 650 rpm, and there is a
very slight miss… I think pulling the plugs is in order, and
probably a set of plug wires…

A lot of guys here, and probably elsewhere, aren’t that
into ‘preventive maintenance.’ If it starts and stops, it must be
ok…consequently, it wouldn’t surprise me if the plug wires at the
least were circa 1993…

Again, thanks for the responses… I appreciate you taking the time
to respond…–

Sounds like a great Jag, Mike.

Most any of them need a few weekends of tinkering, which you already have a
good handle on. After that is usually clear sailing.

Is your a V12?

And post some pics :slight_smile:

Hi Mike and WELCOME to the club! + Happy New Year!!!

THAT’s pretty impressive for 2 weeks! Took me 3 weeks just to change the
plugs :slight_smile: Would you tell me what model # SONY speakers you used. I’d like
to swap mine out also…another 3 months!

I’m sure others will drop by to help you with the lense and TPS. I bought
( but yet to install ) 2 new euro headlight assy’s locally for my
92…$600.00…ouch!

Have a great day,

Hi Mike also new to Jag’s and forum it seems there are a lot of
very helpful and knowledgable folks around. I’ve recently
purchased a 1984 xjs w/ 36k miles v12 I’ve always been amazed by
the v12. I was also drawn in by a previous owner who had left his
mark on the Jag ‘‘walter Payton’’ The cars drives wonderfully needs
very little I hope, it did sit around for a while with very few
miles from year to year. Once I got her home and nestled her into
her garage bay I couldn’t wait to raise the hood and tinker, but it
seemed as the hood came up my knee’s began to shake my palms began
to sweat, I guess you get the point glad your not having the same
problem. good luck–

Hi Mike,
Most of my XJS parts have come from ebay . I am also
surprised at what I find at the local parts house that
really work ! My 1977 is white with the Red interior as well.

Mike,

Before doing the spark plugs I’d recommend carefully checking the injector wiring harness. Unfortunately, it has lived it’s entire life there in death valley and most of them are litteraly cooked to death. The connectors to the injectors are usually either crumbled or broken and can no longer maintain proper contact with the injector. Should you have some damaged, they are Bosch units and should be available locally. If not, let us know and someone here will send you some.

Keep us posted as to your findings!

Thanks for all the helpful comments… I have been on
Ferrarichat.com for over a year, and there are some really helpful
guys there, but not nearly like here…

Oh… unexpected challenge today. When I started it this morning
(cold start) my ‘check engine’ light came on, and stayed on. I
happened to notice the digital display that normally shows the time
when, briefly, to FF13 (if I remember correctly).

So, time to go to Mr. Palm’s book (and I mean BOOK, since it
printed out all 732 pages last night) and see what’s next…

I still drove it to work (about 15 miles), and except for a slight
miss (plug wires?) the temp stayed good, the alternator was
charging, and the oil pressure was up. So, I figure it must have
something to do with an ECU… I know on the Ferrari, once in a
while, it just needed a clean reset and clearing of the codes, and
all was well…

So… watch this space!

In reply to a message from Earl Kiker sent Thu 8 Jan 2009:

I would recommend at this age just replacing the injector
wiring loom, if there is any sign of cracking of the
insulation or connectors.

I had my old loom crack internally, shorting out one bank so
that they were all wide open, stranding me in the middle of
nowhere and nearly setting fire to the cats.

On the subject of idle, these cars often have a lumpy idle.
What happens when you raise the RPM to, say, 1500? The
engine should smooth out completely, with no regular
vibration. If you pull one plug lead, you will see what I
mean. There is a detectable vibration at all RPM with even
one cylinder not firing.

Welcome to the best forum out there!

Hi Mike,

I would suggest putting your model year and engine in your signature,
as there was a 4.0L 6-cylinder as well as V-12 used in the same
chassis. I understand from your previous post that you have a 5.3L
V-12. That makes it particularly important that you post your engine,
as in the US, as I understand it, the 5.3 V-12 was in the 92 models,
all 93 models had the 4.0L 6-cyl, and the 6.0L V-12 was used in the 94
models.

Fault code 13 for the 5.3L V-12 with diagnostic display (92 model in
US) indicates an EFI ECU Pressure Sensor fault. The ECU contains a
sensor to which a vacuum line from the intake manifold or balance pipe
is connected. Among other things that can cause this fault is a bad
hose or break in the line between the manifold and the ECU.

On my 89 model, there is a fitting on the rear of the balance pipe
(that connects the rear of each intake manifold) to which a hose is
attached that runs downward and rearward at the firewall, to go
underneath the car and to the ECU in the boot. On the 92/93 model, a
different ECU is used, and it may be that the vacuum line is attached
to the intake at some other point.

Perhaps someone with a 92 model can verify the intake/balance pipe
connection point for this hose?
