R33 Idle Issues & Stalling

[Beelzebub89]

Hey all,

I need advice on what could be wrong with my car. I'm a new skyline owner and only had the car since Tuesday. Ok so heres the problem. When I'm driving and I come to a stop at an intersection etc the revs drop right off to like 200rpm. Engine recovers and it settles at around 500 - 600rpm. Is this the correct idle? I thought it might be a little higher but I'm not sure.

The car has also stalled a couple of times when parking or pulling into the garage. I have checked all the hoses. Found 1 hose with a crack that has been replaced. Any ideas?

Should the boost gauge read 0 because at the moment it reads -20 vacuum. Its an aftermarket boost gauge aswell.

Thanks in advance

about -20 at idle is correct

i'll let the others get you for the atmo BOV - dont fight it

about -20 at idle is correct

I have found when the car is cold it will be around -20 but at op temp it should be around -50?????

stock bov. pretty sure its plumbed back. im goin to clean the aac valve tonight when i get home because it sounds like that causes a lot of issues like mine.

While your doing the AAC take your AFM off and give it good spray with electrical contact cleaner, and let it evaporate/dry. It could be dirty and contributing to your problems.

Or possibly a sticky bov. happened to me when I first put the turbo motor in the pulsar.

It be your plum back bov or the stock one has been blocked off so it makes a cooler dose.

the vacuum of a motor shouldnt change once its warm

the vacuum of a motor shouldnt change once its warm

if the engine is stuffed it probably will - the expanded pistons seal and create more vacuum.

Its a possibility

possible yes,

but would still have a max of about -20 changing from perhaps -10 or so
