Vacuum lines in 4AFE (Recently swapped)

[syedbasitalishah001]

Brother there aren't any good mechanics in Karachi either for 4AFE. Or I might not be aware of them.
If you know about the vacuum lines of 4AFE, please guide me. I believe there is some problem in your electric system. Maybe your alternator or weak battery.
Thank you

Sir, you mean vaccum source line for power steering (shown in pic # 3 ) should be connected to intake manifold (in one of its two metal pipes)..Right?
Related to same topic... AC idle up Assy has two hoses, one is connected to Intake Manifold... what about the other one? Where should it be connected? Kindly help?

on 4 and 5AFE engines, there is a metal pipe under the intake manifold, it connects nearto the throttle body and supplies fresh air.

it has multiple ports to use.

one of them connects to the power steering one, one connects to the AC idle valve.

The other end of the power steering and AC idle connects to the intake manifold (vacuum side) - because both those switches/valves work as air bleed to raise idle speed
