I am a newbie, next step for my tb45e.

[dan_bald]

I have a 2001 tb45e, at idle it is vibrating at certain rpm, already replaced plugs and cables but still the same.

G/day Dan, welcome on board mate.

The problem your having sounds like it could be your TPS (throttle position sensor) needs adjusting.
this is really a job for a good mechanic though.

Are you having any other problems along with this one like is it surging when driving? any additional info will help.


Cheers
Paul

G'Day Dan and welcome to the forum

[dan_bald]

Thank you guys for the warm welcome. Plugs 1, 2, and 3 are filled with black/burned sooth, it look like too much gasoline. I consume more gasoline.
Less power with engine already roaring.

welcome Dan

Thank you Paul, I am planning to replace the TPS by myself. Is there any proper procedure to do this or just replace and test?

There is & you may not need to replace it, thay can be tested & reset correctly But I would strongly suggest downloading the factory service manual (link below) if you haven't already & reading the section that refers to this.

You can solve your problem or just as easily create quite a few new ones if not done correctly.

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.

[dan_bald]

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?

[YNOT]

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.
