Gooday everyone,
I have a 2000 TD Jackaroo and it is currently getting fixed (
united fuel injection) for a idle/rev problem. I was wondering if anyone with a TD jack has experienced the following problems and how they were repaired.
- After driving for long distances at above 100 km/h and coming to a stop the revs cannot stay constant at idle. This goes on for about three minutes before the engine maintains a constant idle again.
- When in neutral and the revs are held at approximately 1500, again the engine cannot maintain constant revs (needle goes up and down slightly).
- In addition to above, when accelerating or driving at a constant speed the engine often has hesitations / surges. This really gives me the ?.
My oil is changed every 5 K (5 - 30w castrol formula R), fuel filter every 10 K and air filter is a K&N. If anyone has any advice (besides selling it!) or has experienced any of these problems, please fill me in. Cheers!

Gooday Banjo,
Yeah I reckon the Jacks a great vehical too. I've tried all sorts of oil during the 80 K i've had the vehical. I used 5-50w
mobil 1, 10-40 magnatec, 10-30w holden oil? and the 5-30 castrol formula R that i'm currently using. The type of oil has not made a difference to my problems (bugger!) but there are definately slight differences between the jacks operation when using the different oils. I found the magnatec to be very good and i was using that for most of the 80 K. Since i've changed to 5-30w formula R I have noticed better performance when the engine is cold, although i'm in
Perth and this will obviously change with your chosen habitat!! Anyway back onto the idle/rev problem, I contacted
united fuel injection and they seem to think it may be the oil regulator switch (they have contacted holden and isuzu and they are scratching their heads also). The other problem i had with my jack were buggered glow plugs. I had new ones fitted, however the plug in the number one cylinder has corroded in there and now on startup i have a cold cylinder which blows a bit of white smoke. Apparently the only way to get the plug out is to remove the head and drill from
the block side!
Cheers for the reply,

My Jackaroo is a 99 SE Diesel and as I live in
Brisbane cold winter's are not an issue , I removed the fuse for the glowplugs as it starts just as
well as when they are connected (direct injection helps) The reason I did this is long term reliability , my previous was a 86 2.2 Turbo diesel and burnt out several glowplugs in the 10 years that I owned it , one of these broke off and went through the turbo
(not happy Jan).
I also run castrol RX super 15W40 once again in
Brisbane no difference in starting to the 5W30 the car came with . I believe the RX is a good oil and plan to keep the vehicle for many years and Ks. Only probs I have had is injector seals which I replaced my self then I received the recall notice to replace the injector seals (grumble grumble)which I took advantage of as they fit a double seal and sleeve with this particular work When they did this work the throttle position sensor failed and the dealer replaced at no cost to me (car has 85Ks and out of warranty so pleased with that ) I love the vehicle and hope for many years of enjoyable driving.

Apparently
United fuel Injection have found the problem with my Jack. The oil regulator switch was replaced and they have said that the car drives alot better and without the surging and hesitations. I'm picking the car up this arvo so we'll see - better ? be fixed, this problem has been bugging me for some time now. Rigor I also recall my car having a new TPS fitted and Holden paid for it if I remember. Cheers!

Good news, it was the oil regulator switch/sensor. Although I still have the smoke on start up and the turbo not spooling up at idle (cold start).bleepoff.
