I wanted to fix throttle hesitating problem so i decided to clean the Throttle body.

but I couldn't find it.

Do you have any information for cleaning throttle body or remove the hesitation?

Welcome to the forum!

The throttle body is located on the passenger side of the engine in the area between the Intercooler and Alternator. It is a little harder to access that the other V6 engines.

With this engine there are a few throttle concerns:

1. Hesitation on acceleration - due to the fact it is drive by wire from the pedal to the throttle body
2. Hesitation on acceleration - due to turbo lag
3. Hesitation at idle - possible regulator valve issue

For the first two concerns you could try something like this: https://burgertuning.com/products/lexus-jb4-tuner

Look for the metal 90 degree connector from the intercooler to the tb, as pictured in the ebay listing below:

Once you find that on the passenger side, the TB is there, and not that easy to access.

The JB4 mentioned above wont help with hesitation. Which I switched from the Jb4 to the D3 Tune, that made a massive night and day difference on any hesitation.

Always good to have options...I wasn't quite sure what hesitation was being referred to.
