If in your crude drawing where you said your talking about #1 or in the picture you have labled "hot chick" That is your air feed to your idle air control motor and your FICD.

#2 is egr and canister purge vaccum solonoid.#3 is pcv port for fresh air intake into the valve cover.

Thanks!@

btw, what is "FICD"?

[NISTECH]

It is a bi metal valve that when cold provides additional air flow to the intake as the car heats up an electircal current is supplied to it to close the valve once it reaches operating temp.

FICD= Fast Idle Control Device

It is the item circled in this pic
