help with vacuum lines

[tooslow240]

hi, ive searched around and looked at the s14 fsm but i couldnt find out how to properly connect my vacuum lines. im from the philippines, the mechanics around here dont want to touch it coz its kinda not common here.



what could that green thing be? and where is the line thats plugged with the screw supposed to go?

i sketched how my lines look like now, its a rough sketch hehe.



are they right? can this cause stalling? because im having idling issues. whenever i decelerate, and press on the clutch my revs would drop to around 200, it just barely makes it then slowly goes up to around 800. i already cleaned the IACV and changed my plugs, but its still the same. im thinking it may be the vacuum lines.

thanks in advance.

You dont need that green thing.Its the stock boost pressure sensor.It would go between the intercooler piping and the wastegate vaccum line.
