My ED 5.0 auto is using a heap of fuel at the moment;{100km less per tank than usual}.when you start it up when it's hot it idles at about 12-1300 for about 15-20 seconds before droping down to normal idle; other than that it seems to be running fine just using heaps of fuel. can anybody give me any idea what the problem could be.

I havn't been able to check my fuel consumption yet, but last week I had a quick tune up done by Ultratune, and they checked the timing (10 degrees out), cleaned the injectors, carbon cleaned and changed the fuel filter. And now it feels like a new car, the car is more responsive and doesn't kickback or hestitate when hammering the loud pedal. Best $300 ever spent, plus now its got the go of a V8!!!!! I can't really give a good comparison on fuel economy, until I do my next highway trip, as my fuel economy is up the shit around town, as Gladstone is so small, by the time you reach 60km/h its time to slow down & I like to have a bit of fun when driving!!
A side effect of having my battery disconnected whilst playing with other things was a note worthy improvement in fuel economy! I have not reset the computer before, nor was I gentle with the loud pedal having done so but I've found that I've dropped from a fairly consistent 20L/100ks ish to 15/16L/100ks ish (all city cycle). I thought the computer maps adjust overtime but there you have it. It's been like that for over a week now.
Definately have a look at your O2 sensors, my brother has the same car as mine with 60000 on the clock and after putting pacemaker extractors on, these sensors shat themselves. Result was hunting at idle and very poor fuel economy.

My brother went through the same exersise about a month ago with his O2 sensors after fitting his pacemaker extractors to his AU Ghia 5.0.
When did you get your pacemaker extractors on ED GLI V8 ?
I also had the same problem with my oxy sensors crapping themselves after pacemakers were fitted. Had to get both replaced and all was fine.....for a while.
I still am getting inconsistent idle with it wanting to rev to 1200 in nuetral for no reason. It happen 97% of the time I drive it. It annoys me but doesnt seem to be harbouring anything. The only way I have counteracted the problem sometimes is by thurning the car off for 10-20seconds and turning it back on and letting the revs die down to normal and take off from there until I reach my destination. Sometimes when revving happens it will stay like that until you turn the car off, other times the revs die normally with no coercing.
Ive had this problem for years and have been trying to fix to no avail. Last thing to check for me is the ignition system. i.e. dizzy cap, rotor, module, coil etc....
