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:

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 pajero 3500 gdi 1997 model, that is light engine check in dashboard and can't accelerate more than 3000 rpm.

ECU has logged an error code. YOu need to read it out with a tester and then fix the reported problem or clear the error code.
ECU goes to safe mode with reduced power if certain errors are logged.

Where can I find the high pressure pump on and the Mitsubishi pajero GDI and the fuel pressure sensor?

I don't think there is a pump, it is done with engine oil pressure at the injector.

Mitsubishi Pajero Exceed 1997 Model Engine #6G74 GDI V6 3500,no power,I suspect its the engine control unit,I order the ECU,but still no power,probably its crankshaft and camshaft sensor.

I solve this problem with Mitshubishi Pajero GDI 6G74 like this: remove the two little filters from the high pressure pump and ,if necessary, insert a external gasoline filter.
