I cannot find anything specifically for tb45e. I have the supplement VII that mentions about tb45e has only circuit diagram and speed sensor.
I am looking for manual specifically for tb45e.

Thanks Paul, I tried to adjust the tps, it only affects the idle speed. I want to add more, this vibration at certain rpm (at idle) is appearing when the engine is hot, the hotter the more vibration.

The first three plugs are filled with black soot (like powder) that can be remove easily.

Do you have any idea how to adjust the air/fuel mixture and also the location of oxygen sensor on tb45e?

Oxygen sensor will be in the exhaust manifold. Although it is possible for the oxy sensor to be causing the fault, it seems unlikely as it would be affecting all 6 cylinders, not just 3.
Air fuel mixture is set by the computer and cannot be adjusted.
Have you checked the compression or had the injectors tested.
I would also try to retrieve PCM fault codes and see if that gives you any clues, but be careful what you do with the results. If you have a mechanical fault, it may throw one or more of the engine parameters out causing the PCM to log a fault code, when there is nothing electronic causing the fault.
