Why is it that every time I read your dribble I have the urge to put on
rubber gloves and play proctologist.

Heres a question- i found a tiny solenoid that has vacuum connections
to the charcoal canister, to the throttle body, and the egr control -
is there a test procedure for that one? its really small and i dont
know what activates it- but it may be the source of the AIR LEAK- any
suggestions on troubleshooting?? thanks.
PS- i replaced ALL small vacuum lines and checked the brake booster
etc for leaks- found none.
