vacuum leak 1000 rpm idle
i tried the carb cleaner test around the throttle body and pcv connections. i took off the brake booster line and it looked fine.
so a few questions here.....
what is this tube that i have removed? not a vacuum line correct? i ran engine without it and no change in idle
this one i could feel the suction but when i took it off there was no change in idle so that makes me think there is a leak here
the previous picture brings me to this one, what is this? something to do with the air pump i no longer have? its just laying in my engine bay, do i need it?
any other vacuum lines i need to check?
thanks

Pic 1) Thats the suction port from the TB at WOT.
Pic 2) Thats the intake vacuum port to suck in gas fumes from the fuel tank. If not capped it will suck in fresh un-metered air.
Pic 3) Thats the fuel solenoid that should attach to that fuel vacuum port. That solenoid opens and closed when needed to allow fuel vapors to get sucked into the intake.
