99 xj8 4l had misfire #3.
Initial codes: p0300,p0303,p1313,p1316,p1384,p1396,p0116,p0125,p1 000.

Replaced the spark plugs, and all 8 coil packs. reset and started engine.

Now getting codes: p0354 ignition coil D Primary/Secondary Circuit Malfunction &
p1000 Manf Control Fuel/Air Metering, Aux Emissions Controls

Will start but runs rough. Will not rev unless you play with the accelerator.

Any ideas what to try next.

Thanks

Lookin good sittin in the Garage!!!

 

Use this link and go to P0351 http://www.gusglikas.com/images/Auto...J27%201999.pdf . This fault will put your car into a restricted performance that will not let you rev above 3000rpm. Check your fuses and grounds it sounds like a power problem.

 

I will check the grounds etc..
Thanks for the info.

I found a good inexpensive scanner. Actron CP9125 at Autozone for 49 bucks. w/ 10.00 rebate. comes with a cd that allows you to look up codes on most cars.

Check the fuses as well.

 

And forget the P-1000 code. In a Jag, it simply means the "OBD drive cycle is not complete".

 

Didn't find any bad fuses. A couple of the ground were a bit loose. Tightened them up.
Did a hard reset. then started again. Idles ok Runs rough . Checked codes again, coming up P0303 P1313 P0354 P1000

I checked fuses in ds engine compartment, Trunk behind battery and both back seat kicks.

Any ideas?

 

Did you get a chance to look at the link I provided? Relays and fuses for the engine management are under the hood. All your codes relate to ignition and fuel, I would be looking in each area independently for the presents of both. The codes can at times be right on or confuse the hell out of you that is why you need to look at each code and find what is related to your problem. I hope someone with a little more experience can jump in and help.

Looks like the motor is junk.

I found a replacement motor.

4l complete rebuilt.

I got the numbers from the owner.

he said the numbers are:
Off the block: left front if you were sitting in the car.

1st row:991210
then: 22222212
then 2309

My car is a 99 xj8 does anyone know how to reference these numbers to verify what it is and if it will work for my car.

He does not have the car it came out of.

Thanks

I am not sure how you got in this thread, but those numbers are the codes that "blueprint" the tolerances for the crank and bores. If you are changing the entire motor, they mean nothing.

 

Mark, At the risk of being verbally flogged by those with more knowledge than I, I'll go out on a limb and say that sparkenzap is correct with the tolerance observation (2222.....). Having looked at these numbers on a newer 01-02 engine (in my 99xj8), I would offer that the engine in question was built 1999, December, 10th, 11:09 pm. They did move the number location between 99 and my engine. But, I would surmise that this engine will work. It will have nikasil lined bores though (FYI).
No offense intended sparkenzap, I'm far from being an expert.

Ralph-
I am also far from being an expert- I happenned to find a document some months ago defining the tolerance setups.
You corrctly pointed out the date code which I thought was obvious, but looking back, it is important to Mark, since he is near the AJ26 to AJ27 transition, I think.

Mark- I believe the MY 98 -MY 99 cars had AJ26 engines and the MY 00 cars were AY27s. The date code of late 1999would imply that the proposed replacement engine is from a MY 00. So, you need to carefully determine which series you have and replace it with same, unless you want to go through a bunch of stuff changin heads and so on. (Good post on this from AVOS in the XK8 forum, I believe). Look to the archives to find the external distinguishing characteristics.

 

My car was mfg 1/99.

The engine I'm lookin at has code 99/12/10 Build Dec 10, 1999.

It is complete rebuild. Bottom end complete.

The heads are all there but will need to be reassembled.

Nikosil engine. What will I need to watch to prevent problems?

Quality Fuel & proper oil?

What is recommended?
Fuel? Premium Grade How do I check sulfur content? What is recommended levels?

Oil? 5w-30

Thanks again

Again, although it looks like you are OK, I would be extremely sure that you have the same aj26 or aj27 engine. The build dates for cars versus engines are murky.
Look here for ID:

And, how did the rebuilder deal with the Nikasil liners? "bottom end complete" sounds like the "rebuild" might be limited to rod and main bearings only. It would sure interst a lot of us to learn a source for sleeving and new pistons/ rings for the Nikasil engines, as there does not seem to be a reasonably priced solution right now.

 

If my existing engine is a26 and the new one is a27 with steel cyl.

Will it swap in w/ no major problems? Computer change etc?

 

There are some pretty serious differences in the vvt control system. The AJ27 has continuously variable timing while the AJ26 is apperently "two position". The cam position sensor on the new engine has 4 pulses per rev, while the AJ26 has one. To swap will at least require ECU and engine loom, but the prevailing "wisdom" here and elsewhere is that putting the AJ26 heads on the AJ27 short block is certainly the easiest way out.

Are they telling you that the replacement has factory steel sleeves? I am not sure of the change date (apparently Sept. 2000 from archive search). so your date code conflicts with what you have been told. I would sure check that. If it was resleeved, what is the source for the sleeving? As I said, there are a bunch of us that would be interested to know for our own rebuild.
Keep us posted. If it makes you feel better, there are a lot of folks here who are, or expect to be, dealing with this.
