You have:

Carbon canister lines (it's located in the rear pass side of the car, underneath), EGR lines, and boost sensor, etc...

You can pull EVERYTHING, even the hard lines located on the bottom of the intake manifold, if you remove it all.

What need to stay is: FPR and brake booster.

PCV I would vent...just crimp the nipples on the bottom of the intake manifold, and then turn the PCV outlet down.

You will get codes unless you put a resistor in the EGR temp sesnor wires. It's easy...

There are several solenoids that the vacuum lines run through as well...they all go with the lines.

Plug the port on the bottom of the TB, and any other open lines, except the vent for the gas tank.

Later - Brian

And then plug the open ports...

Pressure test the wole thing when you're done.

Nope. The brake booster line has a check valve so it won't see positive pressure.

It doesn't. It see 0PSI as it would on WOT with an NA car.

Don't have my FSM with me. If you do, look for the part on sender testing. The EGR temp sensor should have some resistance range it works on.

Nope, it ain't. But it is a good idea to make sure the check valve is working alright
