G'day Greendog....howya goin'??
Only thing I can suggest is that maybe the aircon pulley has seized-up and is causing such a load that it's dragging the revs down. If it only does it when the air con is on, maybe you'll have to just drive with the windows down and the air con OFF.....just like us patrol owners have to do when the old 4.2 gets a bit hot under the collar!!!! hahaha
Sorry I'm not much use to your problem.....hope somebody else can help you mate,
Cheers
Roachie

Hi Greendog
When the air con cuts in there is a solinoid on the throttle which boosts the engine revs to allow for the extra power draw of the air con my guess is the solinoid's shagged
run in neutral and switch the air con on and off the revs should pick up a little if the solinoid is working if the revs drop by a couple of hundred revs thats your problem

Greendog OK its not the air con, if its an EFI try cleaning your oxygen sensor - especially if you have an oil soaked air filter- or the enging is at all smokey
The sensor gets a fine coat of oil or other crap on it and on longer operates properly when backing off as in changeing down you may be flooding the engine the extre load of the aircon could be all it takes to stall then it looks like its the air
has your fuel consumpion gone up ? does it seem to have less power?and is There a puff of smoke when you run it at high revs for 30sec then back off? all these can point to a faulty oxy sensor

Hi GREENDOG , is it petroll, diesel 6cyl or 4cyl, EFI or carby? This may help with the diagnosis.

Hi Greendog. You may have a prob in the throttle body, they get choked up with sludge in the idle bypass section, also the stepper motor that controls the idle mixture gets sticky. It is not a big job to dismantle and clean it out with carby cleaner, this is probably the first thing to try as it is a fairly regular service item especially if you have a few k's up

Greendog,
I had a vehicle running on LPG that did this, was an LPG problem.
Are you on LPG?

Hi Green dog
I would go straight to the ISC (Idle Speed Control) motor.
We change heaps in the mitsubishi range including magnas.
I buy from AFI in
Sydney. Australian Fuel Injection. No body can beat their price.
You have 2 types, normal and bull nose type. Yours being 3.0 litre should be the normal type. Expect to pay around the $165.00 mark for a remanufactured one.
5 minutes to fit but recommend to clean throttle body as
well.

I just remove the throttle body and clean it with carby cleaner, usually in a pressure pack.
You would have to ring afi as I am not sure if they have branches in other states. The only drama will be they are exchange.

OMG!! I am not insane or just a bad blonde driver!!! You see this happens to me!
I have a 1993 SWB 3Lt V6 EFI Pajero. I have only had it since my dearest one bought it for me in April and have only just started to use the Air con.
I had to replace the battery a couple of months ago so the first time it stalled on me I thought it was the battery for the first split second and then it started again no worries so figured I had done something wrong to cause it to stall.
Having driven around a bit more with the air con on, I have discovered exactly what you said. When you go down the gears it stalls, most often if I put the clutch in to glide to stop.
Until now I thought it was my bad driving :) This is my first 4WD so I was open to the suggestion.
Please know that you aren't alone and I too would welcome any suggestions.......so that my dearest one can carry them out of course....:)
