What should I do with this hose?

[GTRSOAR]

I have a small plastic box with the greddy logo in the plastic next to the boost solenoid. It may double as an optional boost controler. I send pictures tomorrow. It only limits the boost via the gauge in the interior. It only ever goes up to 1bar

Car ran well, back to full boost, the only thing is that the revs still fall to 0 when the clutch is held in. This never happened when I had the BOV done, that was months ago but started when the piping kit went in. When the clutch is held in it falls to 0, stutters and juuusttt gets going again. About one in every ten times it'll stall completely. Very dangerous because I lost power steering in a sharp corner :S

Sounds like classic bogging down caused by a BOV vented to atmosphere.

Run recirc.

Ya recirc is the only way to go, maf cars run like crap vented.... Nissan didn't spend all that time making the piping for fun...

Thats weird because thats a classic problem caused by sudden enrichment using a vent to atmosphere BOV. I''d plumb the recirc back in and try it to see if it makes a difference.

When the idle stabilizes where do the rpm sit ? could also be a dirty AAC valve.

i'm glad you found a spot for the bleeder hose! and good to hear your boost is back.

does the car want to stall when at steady idle? -small leak... educated guess because you recently changed piping. technically, could be many different things

or

does it only stall after reving and returning to idle. -BOV... it might have been stiff from sitting on a shelf somewhere. now it's operating more freely. allowing more air to vent.

[GTRSOAR]

Its not BOV related because ive had that Tial 50mm in for months for this only started happening 3 days ago after the piping went in. And now im back to only .7bar, not .9 ( I hit .9 on my test drive once, then never again. It climbs steadily then dead stops at .7

As for the stalling it only happens when the clutch is put in at around 2000 rpm or above. It always steadies at 1000rmp, but it always drops to 0, almost stalls then holds at 1000rmp

hopefully it's just a small leak.
i feel your frustation.

Well ill be taking to my techanic/buddy/gtr specialist, so find my boost leak. Could an air leak cause that stalling issue too? Its hard to explain but when you shift at say, 4000rmp, you can kind of 'ride the rpms's down' as you engage the clutch to the next gear? Well I cant do that, its like the engine cuts firing completely as the revs drop which would explain why they always drop too far. I have to give it gas everytime I shift up a gear.

Anyways, ill look for this boost leak with him this afternoon, hopefully well find the boost leak and any other leaks which are causing me issues :S

[GTRSOAR]

It would have to be a pretty big leak to cause a .2Bar drop though eh?

I think two things that contributed to the problem.
1. The BOV did not shut quick enough or the BOV did not seal good. (Air leaked out, so too much fuel in your engine)
2. Better intake piping makes the air easier to back out of the MAFS after the throttle was shut. (Air was measured twice, then again, too much fuel in your engine)
