Question about 2003 Holden Jackaroo

1 Answer

1990 holden jackaroo. 2.6 petrol. automatic trans. has rough idle, and occasionally loses power while driving. idle seems like it is an ignition problem, but have already replaced plugs wires distributor cap and rotor. while driving it seems like the power loss is due to fuel, but already replaced fuel filter. when I unplug the primary o2 sensor while the vehicles running nothing changes at all. could this mean bad o2? again this is a 1990 jackaroo. the listing only let's me put it as a 03 for some reason

The engine may have a intake vacuum leak. A defective O2 sensor has no effect on engine idle or performance.

SOURCE: I want to know where the oil drainage plug is on a 1994 Holden jackaroo

I believe the 3.2 is a Honda/Acura engine and not a Isuzu engine. Are you talking about changing the engine oil or the transmission fluid? I ask because you state "the oil drainage plug" but later you mention the Automatic transmission.
As for engine oil plugs, they are almost always found low on the engine oil pan, sometimes facing the front (like my Jag), to the side (like my Ford Ranger) or to the rear like my 90 Acura Legend 2.7L V6 did. Most have a bolt with a washer that should be replaced every time. If it doesn't look like a large hexagonal bolt head it could very well be a rubber plug that is pushed in. Not a good design in my humble opinion. If you change the oil be careful not to do it when the engine is hot as the oil is also quite hot. I believe in doing it when just warm, more drains out. I find it beneficial to drain about a quart out, put the drain plug back in and add a quart of Gunk or Snap engine oil slush, start it (but don't rev the engine & DO NOT DRIVE THE VEHICLE) and let it just idle for 15 minutes. Give it some time to cool then remove the drain plug and let it drain out. Next remove the oil filter. Always ALWAYS pour fresh oil into the new filter a couple of times before screwing it on, and spread a little oil on the little rubber gasket on the filter first. I recommend synthetic oil for any vehicle as it doesn't break down into coke (hard rock-like black stuff) like conventional oil does. Those coke deposits are engine killers. I like Mobile 1 extended fuel economy. Synthetic costs more but lasts longer. If using synthetic were to only extend the life of your engine by two or three years, I consider it well worth the added expense. It should reduce wear in the engine, keep it much cleaner, make it quieter, and give you better mileage because it's slicker (less internal friction).

I have a 1998 holden jackaroo SE automatic petrol car and it starts,reverse but when u put it in drive it doesn't drive if you press on the winter drive it goes so what's causing the problem?


Get a trained person to check the transmission. If it goes backwards but only goes forward in winter mode then there is a trans fault because auto's generally pull away in 2nd gear in winter mode to reduce wheelspin.

I have holden jackaroo 1996 check trans light comes on and flash ...and the battery volt indicator goes from around 12 up to 16 when it flashes and lose power. .. help please...


check the output of the alternator as the regulator should be set at 14.5 volts max 16 volts is way to much for the electronics and amounts to a power surge.

1990 Jackaroo has a fuel problem that has me stumped, while driving and you accelerate even a little bit and the motor almosts chokes and loses all power, but while idling it will rev up well and idles...


1990 Jackaroo has a fuel problemThis is usually due to fuel starvation.
  1. Replace the fuel filter.
  2. You can check if the fuel pump is working when you disconnect the filter hose.
  3. Place something under the filter and the disconnected hose and get somebody to turn the ignition switch to the on position
  4. The fuel should be pumped through the hose that is connected to the back of the car.
  5. If the front hose is disconnected the fuel flow will be minimal or none at all.
  6. When you put the new filter in make sure the flow arrow is pointing the same way as the old filter was.
  7. If no arrow is visible connect the (Front is " < " this part of the arrow) and (Back is Shaft / Straight part of the arrow)
  8. The Front of the filter should be pointed to the front of the car
  9. the Back of the filter should be connected to the hose that is connected to the fuel tank.
If there is no petrol being pumped out when the filter is disconnected, this usually means that the fuel pump is not working and needs to be replaced.

Rough idle in park occasionally and while driving seems to shutter has stalled a few times


Your ignition coil might be bad. If it is happening after it rains, check the distributor for moisture. My ignition coil went bad on my 98 jetta.

If you replace the ignition coil, it runs rough for a little bit and it needs to sync. Just drive it around a little bit and it should steady out. If it doesn't take it to a mechanic.

Good luck.
