3VZ-FE engine - reference photos or diagrams for connections to intake manifold?

[hotspur]

3VZ-FE engine, Camry LE V6, 1992.

Can I get a set of reference photos or diagrams, for use in checking that my 'mechanic' has not inadvertently 'crossed' any connections to/near the intake manifold (after replacing the head gaskets)?
[I know, for example, that the 'mechanic' had to bend one metal tube in order to make it connect with a hose that leads up to the EGR part of the intake manifold.]

Miles-per-gallon are down [from about 21 mpg (US) before the head-gaskets replacements, to about 15 mpg afterwards!].
Also, the engine is not very smooth when idling.
The engine seems to falter and vibrate unduly (even if not grossly) while idling, for example at red traffic lights.

Note, I did re-adjust the Throttle Position Sensor (TPS) to within specs - after which the 'responsivity' of the engine (on the road) improved enormously - but I'm still left with the concerns and issues described above.

Thank you - there's nothing relevant to the problem there. PM sent.

He he . Sorry that happens when you don´t read. Hopefully the other thread will help in something

That's OK, thanks for trying anyway.

By the way, in this string, I would welcome "amateur" photos of all the connections to/near the intake manifold for the 3VZ-FE, as well as published photos/diagrams.
