Idle/vacuum R32

[fazz]

ive recently bought a BOV for my r32 skyline , and after getting it installed, and driving, i keep losing idle if that makes sense and the car just stalls outa nower.. i think its called losing vacuum. anyway after adjusting a screw on the BOV the problem was fixed, but again after a few months, every now n then my car stalls, for example il have it in 3rd gear on 4rpm, then put it into neautral, and u see the rpm rush down to nearly zero and the car nearly stalls. however, next time i start the car and drive the problem is fixed and i have a smooth drive.. the vacuum pressure on the stock gage also varies time to time..

anyhow, my idle has kinda dropped from 1 to about 800, so i wanna increase it .. where is the idle adjustment.. its sumwerrr lol but i cant find it?

can anyone help?

if the new bov is not a plum back this will cause the stalling problem due to the air flow meter not getting the air from the bov (this is tuned into the comp from factory.)

as for the idle adjustment, its at the back of the plenum round thing with a flat head screw driver adjustment facing the driver side.
