Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

Looks like the TH butterfly was never cleaned before.

As this NSX is the later model, the blowby gas passage is different from
the earlier models and thus, has the advantages in keeping the TH body clean
but still, it was really dirty.


So, before starting the engine, cleaned it as much as possible and then
fired up the engine and used short blast of cleaner several times.

PCV valve on this model normally stays clean but as a standard procedure,
cleaned it as well while running the engine.

Now it’s very clean.
Ideally, you should clean it once a year.

Reset the ECU and will check the idle rpm once I have managed to drive this NSX again…..
No brake at the moment……
Where are all the calipers and brackets?

Everything back in place and the engine bay is done.
