Gday i have a 32 gtr and it has a stalling problem.Since the car ran normal we've changed plenum fuel rail and reg.Its a sard reg and dual entry rail.

I been pullin my hair out over this thing

ive check for vacuum leaks

adjusted fuel pressure with out vacuum line to 43psi

adjusted blow off valve

done boost meisters fuel pump earthing trick

changed plugs

cleaned afms

checked cooler pipes for leaks or splits etc

disconnected o2 sensors

played with tps

this sard reg is abit queer pressures jump all over the joint,Ive adjusted the pressures to many times so im thinkin fuel reg f***ed?I dunno lol anyone with any info can u plz help me

doesnt matter if its in the garage free rev drop the rev straight of wants to stall til it seems like it gathers fuel pressure again

i took it for a drive was ok through the rev range til i back off to slow for intersection and stalling again

anyone plz help desparate over here

I'm assuming you've got a fuel pressure gauge. Why not free rev the car and watch your gauge, see if the pressure is falling. I'm going to say either dirty aac/iacv, worn gasket, vacuum/manifold leak. Do a pressure test on the intake then the manifold. Do you hear any hissing sounds in the engine bay on idle? How much vacuum does your car idle on?

Because regardless if it stalled or not, running a atmo BOV on a airflow metered system is just plain stupid.

Let me guess, you did it for "the sound"

I'm guessing that you didn't even need to upgrade the FPR or the fuel rail?

yeah mate got a gauge,which gasket u say on iacv or manifold.Ive checked manifold with wd40 and no hissing at all from then engine bay on idle.Can we remove this iacv with removing the plenum?

oh n thanks for your positive feed back man

Why is it stupid? I'll explain it for the 10,000th time. Yes, its been answered about 10,000 times.

I've actually got a copy and paste space where this is. Read on.

I love these threads.

You love the noise - and put the BOV on the car to be a wanker. Its scientifically proven that if you're a wanker, the first thing you do when you buy a Skyline is install a vent to atmosphere blow off valve, to advertise the fact that you are indeed, a wanker.

Do you even know how the Nissan air intake system works? There is an AFM that measures the air entering the engine. The Stock BOV recirculates FOR A REASON. When your duck whistle, twisty whooshy twirly, dick pulling, sparkly, spinny, shiny, noisy, fuleh sic, wank off valve opens, it dumps air that the engine has measured and allocated fuel for. When only half the air gets into the cylinder because the air it measured is at the street corner where you sped up erratically and backed off because you saw some women on the corner, thinking that when they heard your BOV they'd get naked and run and dive into your car, the engine is now overfueled and under oxygenated, and stalls, backfires, and carries on. You know why? Because you've created a MASSIVE AIRLEAK on a system that will not run with airleaks.

Do you like that fact that you will foul your plugs constantly?

Do you also like attracting the cops attention?

Do you like the risk of being defected and having to pay money for a BOV that didn't need to be there?

Do you like the fact that you are just making skylines more hated? (And don't worry, its almost a guarantee that you'll drive through the main street of town making it release "because you like the wank off sound")

Do you like it how women love the sound, get naked and dive into your car as you drive past?

Do you think SAU will be happy about another "My car is running rough, I only installed a duck whistle, twisty whooshy twirly, dick pulling, sparkly fuleh sic wank off valve" thread

They should create a database script that bans people that install BOVs "just for the sound" or complain when their car runs rough...

I'm was running 300rwkw and had the stock BOV.

Good luck with it though.

P.S. I'm a tuner.

And I refuse to properly help someone complaining about a stall problem when they have a ATMO bov. Its an airleak. Just like pulling a hose off and leaving it off. Except it only leaks air when you back off the throttle.

I just love pointing it out to people who have no clue of this air measurement system and post countless threads on SAU.

so as stated b4 you copy n paste a hole load of shit to my urself feel good.CAR RAN PERFECT WITH ATMO BOV FOR 2 YRS B4 FUEL UPGRADE.Your car ran 300kw at the wheels congrats would u like a medal now serioulsy mate lets try get to the real reason the car is runnin like poo

and one other thing. Sard FPRs are crap. I refuse to tune any car with one attached.

Get something quality.

also if u know its the reg

why didnt u just say soand what would u recommend

Becuase I posted this before:

Problem would have always been there - You've just made it worse by adding more factors in, like a crap FPR.

so really if the problem has always been there why did the car run perfect for so long mate.Give a decent answer this time

p.s where do u tune and who do u work for so i can come get my car tuned by the most knowledgeable guy .... in the world.

I'm not even going to bother feeding your ignorance.

AFM measures the air.

BOV dumps it.

ECU injects the amount of fuel required to amount of air measured.

A lot less air than amount measured gets into the cylinder due to being dumped for a "cool sound".

Too much fuel.

Car has rich condition.

Car stalls \ fouls plugs \ doesn't behave properly.

BOVs only open and dump air when you back off the throttle. You're having a stalling problem when you back off the throttle, correct?

By f**king around with the fuel system, adding most likely not needed and a crap quality FPR, you've made all running conditions worse.

Good luck having no clue and being an ignorant dickhead.

aaaaaannnddddddd *drumroll*

You answered your own question.

So, eat a dick.

But as I said, I refuse to properly help someone complaining about a stalling problem with an ATMO bov. I don't even care if that isn't the problem. 99% of the time, it is aggravating it.

    • My idle is set at 950rpm though - Moving the timing around 20 degrees is not really what I'd call a calm idle. That said... neither is chop, by definition. The LS ECU likes to adjust timing to hold idle as opposed to air. It'd work, but generally speaking there'd be a discrepancy in the base idle and the IACV would want to move the timing around anyway to maintain said idle. I think I'm just going to keep the timing steady anyway. Preserve my engine mounts.  My aircon is now officially regassed. As the guy was reversing I noticed my reverse lights do not operate, along with my reverse cam. This is a bit distressing, because 100% of guides talk about which wire to connect to backup cams as "the goes with the [other color] wire". Often when doing conversions. Unfortunately the R34 colour wires aren't documented Unfortunately I had a T56 Magnum gearbox with it's reverse switch, which also isn't documented. Unfortunately there's definitely not documentation for people with both of these in the one car. Unfortunately I forgot. After many hours of this, I have a reverse cam and reverse lights again. The wire going through the trans tunnel to the reverse switch had broken. Upon inspection, it looks like this one wire had about 7 spade terminals and extensions in it.. for reasons I cannot possibly comprehend. I also spent the 750 hours required to clean up the wiring behind my head unit which now looks like this: This is a monumental improvement relative to what used to be there WRT triple gauges, head unit, traction control, wideband controller, and whatever the f**k OEM stuff still exists there in various states of connectivity/needed. Next step is to check in at the Exhaust shop to see/confirm how much clearance I have, to decide what mid mufflers or 'resonators' (which are just straight through, narrower mufflers) I can add and hopefully cut out a lot of exhaust leaks, pinhole, v-band or otherwise. But first step will be to 'take a look' before the next step.
    • Fark the AFM card and Nistune, Haltech Nexus S3, DBW, cruise control, flex fuel, dis dat.  
    • It's most likely the bolt/bush where the cover bolts back wore and allowed cover to move forward.
    • Still haven't put the injectors and R35 AFM in so we can tune the bloody thing for the HG highflow it got mid last year! I think I can forecast the upgrade path to a bigger twin scroll, external gate, Haltech, flex setup, Samsonas, dis dat, etc will be .... a while away!
    • Should have taken that opportunity to slot in a twin scroll turbo setup. Maybe next time.
