looked around didn't find anything regarding this, similar but not the same.

so ima keep it short n sweet.

I drive it to work everyday, but i have to leave my car in what ever gear or down shift (doesn't matter) and let it roll to the light so the rpm go down to about 700-1100rpm's before i push in the clutch and it will idle fine but if i push the clutch while it above the rpms posted before while coming to a light or stop sign it just dies. then i have to start it up, and it will crank over and i just have to give it some gas before it will start up. then i have to lightly let of the gas to where it at 700-1100 rpm before it will idle fine.


i hope this makes sense and thanks for the help in the mean time..

walboro fuel pump
750cc injectors
apexi ecu
z32 maf
bov to atmosphere
and other stuff that i don't think that will matter.

Sounds like your AAC valve could be the culprit. Check this out

This right here. I had the exact same problem when I switched to vent to atmosphere and going back to recirculated bov fixed my problem.

i dont even have my sr20det swap in my s14 yet and being the whole world of boost is new to me. So from all my reading about bov's and what not it seems like recirc is the best way to go...not in all situations but with my sr20det being stock i need to recirc
