Stalling When Changing Gear \ Testing For Vacuum Leak

[Tabs]

hi skyliners

my skyline has developed a issue when i change gear 3000rpm and aboue and leave the clutch in and the rev's drop it come completely down and stalls

if i change around 2000rpm or leave it in gear till around 1500rpm and then put the clutch in it holds an idle ok

it also doesnt stall when cold

it got alot worse when i returned the PCV system back on due to an extreme old burning problem when idling for over 2mins which fix the old burning but stalls more often

it doesnt stall and holds the idle if i give it abit of gas and slowly release the pedal

ive tried uping the idle gone over hoses and hose clamps , tried engine start on joiners

there is no BOV at all ( no port at all for one) :S which i plan to put one on soon.

any ideas or other easy methods to DIY check for vacuum leaks

its a r32 gtst with to4e external rb20det front mount new tps and new airflow meter new fuel pump and no fault codes coming up

coil packs are a lil lazy but still shouldnt cause it to stall

cheers craig
