Hi Baldivis Boy,
I have had the same model Jackeroo for some time (165,000km). I have just traded it for a Cruiser. Not because it was not a good vehicle but because we were begining to find it's 4wd limits (probably went right past them a few times!). Ours has been around,
Kimberley,
Cape York and large areas of the SA deserts.
We had a similar problem at about 140,000 (and a similar problem a few other times) along with intermittent lack of power. There are a few things that it could be or are contributing factors.
1) The plugs are meant to be replaced at 100,000. Lots of mechanics leave them till they die. They are reasonably expensive ~$20 each. I have found that replacing them at about 80,000 was a good idea. If you have the originals at 110,000 I would definitely get them replaced.
2) The fuel filters are the same as on a commodore so if you have been anywhere with dirty fuel change the filter. It is on the drivers side, just forward of the rear wheel on the side of the chassie. Be ready if you do this yourself as the fuel pours out when it is disconnected.
3) Injectors may need a proper clean. This is not a Wynns pour in solution. You need to get them cleaned properly by a mechanic.
4) We also had this problem when the oxygen sensor was stuffed. It ran very lean and would stutter and cut out if you tried to accelerate. Eventually the
check engine tell tale will come on.
5) You may find that there is something in the tank and that the fuel pump is picking it up then dropping it as the engine stutters. If you fill the tank and the problem goes away it would be worth while getting the tank flushed. If you only ever partially fill your tank it may be varnished. Apparently this can be cleaned by filling the tank with Hi Octane fuel ie Ultra etc. I never tried this but it is meant to work because the Ultra fuel has less impurities.
6) You may find that the injector filter is falling apart. They are meant to be replaced every 40,000km (not quite often enough really)
You may find you need to do a few of these to resolve the issue.
Most engine problems are recorded on the engine management computer but your mechanic has to have a reader to read it. The plug is behind the consol trim on the drivers side. Slide your fingers up behind the plastic and you will find it. This is not always easy. It took me 20 minutes to find it the first time. It is a rectangular plug about 3x1 cm. If it is really dusty chances are no one has ever used it.
While I have found the vast majority of mechanics to be pretty upright and honest I have been to one or two establishments that had a very good reputation but were real crooks. For example, with a previous vehicle, I returned to my original mechanic after 3 years (he had moved too far away) and when I picked up the car he was a bit hot under the collar as the oil filter and air filter had his initials and the km written on them from the last time he had serviced it. I had been billed for these items at every service between times.
Jackaroos are normally reliable vehicles. Most of the issues we had were because we really used it off road.
If I was you and you have a mechanic you trust and who knows a bit about 4wd's get them to have a look. If for no other reason than to get a second opinion
Steve

Hi Steve the Jackaroo in question is a Diesel but the DLC is the same in both vehicles and the method of retrieving the codes is the same.
cheers Dave L.

Didn't notice the TD oops. Agree that the management sytem is the key. I also notice Baldivis Boy is a bit sus of the dealer. Should go somewhere where they use the technology not fight it ther whole way. The dealer should have the Holdern CD that gives them the list of things to
check (plus how to do it).
