Hi all, I'm just chasing info on a difficult problem to solve, in relation to our jackeroo.
Day to day driving is fine but when you go for a long drive of more than 2 hrs, if you come from the 100kph zone into town and have to stop soon after for traffic lights ect, the damn thing idles ruff to the point of konking out more often than not. The vehicle is a 3.5lt petrol jackeroo with full log book servicing, it has 100 000km travelled and the platinum plugs were changed recently, they were redish colour at the spark area, apparently some fuel can do this to the plugs?? (this was done to stop the above problem). It doesn't seem to be fuel type as we have also changed fuel suppliers to counteract this.
There seems to be no answers so if anybody has experienced something similar or has any ideas on possible solutions I would appreciate your response.
PS: It seems to happen only when the boss is driving (wife), this could be due to the fact that I never drive this car, or it could have some bearing on the matter I don't know :-)))
Thanks in anticipation Trevor.

Trevor, just a guess but maybe the temperature under the bonnet after doing 100kph gets high enough to heat up the fuel line and the petrol vavorises a bit. You could try insulating it with a piece of split garden hose or some of that foam tube stuff from a hardware, or as a temporary measure, a damp rag. Rus.

good point Russ, but if that is the prob then I would have thought other owners would experience similar traits. Is still worth giving it a go, how much can it cost, have got foam and garden hose in back yard :-))
Thanks Trevor.

Hi,
I know its a different make of vehicle but they do have common principles.
The 100 000 mark seems to bring the problem out of the woodwork in ecu controled vehicles

Thanks Nebster, that sounds similar to what is happening. Maybe ISC, will check it out if the wife can get the car back to me in Brissy as she is in Coffs Hbr.
Thanks again Trevor.

Hi
You may find that it may be somthing to do with the throttle valve actuator.
I had a similar problem when off road and moving slowly in convoy with all the stop start that the engine would stall.
I drive an auto Holden Frontera 3.2l and the engine and electronics are similar.
Apparently what was happening was that the valve was not opening up fully and this was due to electronic rather than mechanical.
Had it changed under warranty.

Roger,
Thanks, I will ask the mechanic about this one as it may have already been checked??
Cheers Trevor.

Remove the ECM Main relay (in the main under bonnet fuse box). Let the vehicle sit for a few hours (overnight). Reinstall ECM relay, start vehicle with air-con/lights/heater etc OFF, when the idle settles down take vehicle for about a 1 hr drive.
Also- check fuel filter. For the few bucks replace anyway.

signman, thanks for the input. If the car gets back to me before every apprentice in coffs hbr has stuffed around with it I might be able to give this a go. What's the logic behind your idea ??
Filter was changed same time as plugs, about 1500km ago. Although I have not ruled out $hit fuel again so may do this filter change again sooner than later.
Cheers Trevor.

removing the power to the ECU will reset it, then after it has reset it will have to remap or learn your driving style and engine characteristics. I had the same problem you mention twice- Once resetting the ECU worked, the second time was a fine crack in the air hose from air filter to throttle body- The crack in it kept making revs slowly fall down to the point it would stall when it came down through the rev range.

Thanks to all,
The computer generated fix is to replace the "mass airflow meter" as this the problem according to the vehicle computer. Apprentice picked up on this down at Coffs and told the better half there would just be a little turbulance on the run home (haha). Car is now back up here and I will check further to see if this is the only thing it could be. Thinking along the lines of crack in air intake pipe or something similar that could upset the computer?? Just more things for me to go through.
Cheers once again and best regards Trevor.

Did it only do this since the service??
if so most likely the air filter was changed/cleaned & the plug was left off (or is loose) on the air flow meter. Its a common error, as it has to be undone to remove the airbox lid.

Bradley,
Thanks but the service was a result of the vehicle playing up, at that stage I thought I had got a dud batch of fuel, so fuel filter was changed but air filter was just checked. The mass air flow sensor was replaced today (2 pay packets later) so lets see how it goes now. Will take about 2 -3 weeks before it goes on it's next run to Pt Macquarie so I'm hoping all will be
well ??
In a way I am hoping your diagnosis was not correct as it cost me both arms and one leg to "have it replaced". I hope it was not just reconnected or I'll be chasing an honest mechanic in a week or two.
Thanks again and best regards Trevor.
