The engine doesn't like the extra stress of the air con unit being run _ there is no way of fixing this _ unless you get a full engine overhaul or a secondhand engine and installed _ the engine is old and the extra pressure on it with the aircon it just cant handle it

SOURCE: seems transmission gear shift problem

Pull the distick and smell the oil. If it's discoloured (black or dark brown) you know the transmission friction plates are burnt and needs a rebuilt.

SOURCE: My car is a 1997

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.

My 2004 mazda b 2300 (105,000 miles) "bucks" when i shift up (usually at about 2000 rpm or less)

The engine may misfire and/or buck while driving at freeway speeds with no fault code stored in the powertrain control module (PCM). This can be caused by an intermittent fault with the camshaft synchronizer assembly. This condition can be diagnosed by monitoring knock sensor data as per Ford service bulletin #05-22-12. Replacement of the synchronizer assembly will be required to correct this concern.

Rpms drop when you shift from parck

There will ne a slight drop of engine RPM when you select a gear as the torque convertor is trying to drive the car and so the engine is loaded up. The RPM drop can be up to 200 rpms on the older cars and less on the EFI units as the CPU makes the RPM adjustment to keep the idle steady.

When does the overdirve need to be turned on

Usually the overdrive should just be left on. It should only come into play when you are at high speeds above 50mph. This is essentially your "5th Gear" and should increase fuel economy. If you leave the overdrive "OFF" on the highway your engine RPM will be higher causing the fuel economy to suffer.
