MITSUBISHI GDI GDI MOTOR 6G74

I help please all experts in Mitsubishi I send them this query, I have a Jeep Mitsubishi Pajero 1997 Motor 6G74 GDI, Automatic Box, is in the best hands we have in Bolivia and we do not find a solution to the fault.
When stepping on the brake and starting up or back the same thing happens when it stops in a semaphor, this fault occurs in cold and hot.
We disarm the engine and also the automatic box, we change rings, bearings, packaging, everything necessary in a repair even changed the GDI pump, acceleration sensor and also TPS. Alta is a bullet, nothing fails in the position "D" and "P" does not fail and regulates 100 points. Even if we put the march without stopping the walk, it is regulated in 850 rpm without air and 1000 rpm with air, and fails much more with the air on. (that is, it is easier)
The scanner does not detect any failure and does not turn on the light of Check Engine, because the computer does not detect failure.
It already has us crazy and we invest a lot of money in trying to repair it, I don't know what else we can do only we need to change the entire engine.
Please, if someone comes up with something your opinion will be very addressed.

Good morning, you should check with a vacuum meter to see if you have no leakage in an empty, you should usually have -16 psi so that everything works well. Greetings.
