Is There A Tutorial For Cleaning Tb Or Replacing Egr Valve?

Replacing EGR on a friends 97 ES, and would like to clean the TB while I'm at it, but don't know exactly how to do so. If no tutorial, I'm going to leave it to Lexus.

No instructions per say. There is various posts on it so do a search. Really it is nothing short of disconnecting battery and then putting something plastic to keep the butterfly open (in TB). Then it is clean with cleaner and wipe down. You can remove it too but I did not.

Also I would clean the IVAC at the same time. Again there are posts on it. Many in fact.

The EGR is one I would also like to know .It is about $140 to buy new.
