Does it use any oil, or lose any coolant? If not, do you make a lot of short trips, then shut it off by chance? If your not using oil, or coolant, then I'd say take it on a long drive at highway speeds to drive out the moisture laying in your exhaust system. Recently had a muffler go on wife's car that does a lot of short trips, and old muffler was almost full of water from condensation and obviously poor exhaust design, that allowed it to build up like that. Took it next night on trip about an hour away. Every time I took off, or passed a car, white smoke rolled out the back. On way home, it stopped and cleared up.

Hi, an intermittent poor idle can be caused by certain valves that are perhaps not always closing properly. Three valves I would check are the EGR, purge, and idle air control valve. The EGR valve can get dirty and start to jam. The purge valve sometimes gets charcoal coming thru the line from the vapor cannister, and the charcoal can hold the valve open when it's supposed to be closed. The idle air control valve is the valve that is supposed to control your idle. If it is not opening properly, the car will not idle right. I explain a lot of this in the following post: http://www.fixya.com/cars/r7427423-fix_poor_idle_high_idle_stalling_fuel
On your car, I am not sure which emission controls are installed. If you have evaporative emission laws, you will have a vapor cannister somewhere in the engine compartment. I believe the purge valve is atop the cannister on the Pajero. Pull the hose off to see if there is charcoal in it. Also look inside the valve where you pulled the hose off to see if it is closed.
There are pictures below of the idle air control valve and the EGR valve. The idle air control valve is mounted on the throttle body, near where the cables from the accelerator pedal attach to the engine. Take the valve off and see if it needs cleaning. Also clean out the passages in the throttle body. Use carburetor cleaner to clean these parts. Also clean out the inside throttle body, if dirty.
Finally, if these valves seemed to be OK, take off the EGR valve and clean it out. Make sure it closes by default. If not, replace it. Please let me know if you have questions, and thanks for using FixYa.

I have a similar problem. It runs a while from cold and then just cuts. I have have changed the TB twice now with no change. I cant afford a new TB. Did you find a solution to your problem?
