hey guys

my stagea has developed a f**king annoying problem of just turning off. as in engine cuts out, but all electrics stay on (lights, radio etc.)

wtf is it? almost drove into a f**king pole when it decided to cut power mid corner. dunno how i stopped it...

car feels a little sluggish lately too. dunno if thats related or not. ive noticed now that when u goto take off, you can feel it hesitate. is that just the boost when it goes from 5-7 or whetever it is? ive never felt it before

ive been told it could be fuel pick up related, where would i look?

ive cleaned AFM thinking it was that for some reason, didnt fix it.

it only happens in mornings too, grumpy f**k.

im at a loss at the moment, and its got me f**ked what to do.

ny point of putting the nissan diagnostic tool on it to see if it shows a code?

hope u can help before i burn it to the ground!!!

cheers

jarryd.

hey jarryd,

i have the same problem with my R33, i only noticed when i installed a turbosmart boot tee and BOV.. it was really bad when i first put it in then my mechanic said i needed to block the the vent from the original plumb back BOV... this worked but it was still cutting out, he also cleaned the throttle body which fixed it up a lil bit more.. it only cuts out maybe once every now an then, getting it fully serviced next week hopefully that may fix it..

in the mean time if you find the solution to this shitty problem please lemme know,

thanks

make sure your battery leads and connection is clean, and very good & tight (as in a very good electric connection)

stock bov?

I had this happen, like, 3 times in 5months while I used a GFB Stealth FX plumb-back BOV (from xmas to end april)

after replacing bov back to stock (put stock bov in vice and compressed tophat spring) and cleaning battery connections, its all good again.

but yeah mine went mind corner and I wasnt happy. lucky it was city street and was under 20kmph

Back somewhere, a couple of years ago, this popped up.

The day I picked up the S1 i drove 5k to a servo and she cut out while turning in to servo. There was SFA on the gauge and I thought "outa gas". She started and got to the pump.

The compliancer said "maybe shit petrol in the tank". Anyway it was fine for a couple of weeks. The bingo, it happens again.

Arf u#k, now what. Started again no probs. Got home and did the ECU reset. Disco the battery. Ignition on, pump the brake 60 thousand times. Re connect. Hey presto, never happened since.

Personally I think it is Gremlins from the #5 Factory.

If you're running an atmo BOV or standard BOV is blocked off it's making the AFR's go bonkers.

revert it back to standard if this is the case and then see if it gets rid of the stalling - I had this problem a few months back.

Hi

I am also having a similer problum. fueled up friday on the way home (same survo I alwayes use) the car runes smoothley until i want to overtake then it feels as though it is on the rev limiter.(at this point the engine has not cut out). I was toled it might be the AFM so I borowed one from a frend but it stil does the same thing.

Anything else I could try

Sorry if I hijacked the thread but I thort it might be related

Thanks

brendo - fuel filter was done last servie, but i will try fuel cleaner/octane booster.

just had car at my local nissan dealership, had the diagnostic hooked up to it, AFM code came up.

been told that Y61 Patrols with the 2.8l turbo diesel engine have the same AFM has the stagea/skyline.

on the hunt as we speak

cheers for your help

jarryd

edit: are all RB25 AFM's the same? or is there a difference between them?

stageas run S2 RB25 motors, am i correct?

first off:

take off the lid of the afm and clean it up, resolder the connections

should fix it

other option is to buy one 2nd hand off sau for $50.

ask around in the vic section if someone can give you a hand to re-solder your current afm internals

Yep, Jaryd, the s1 Stagea runs the s2 R33 engine...

Also, run some (carby) cleaner through the AFM, it might help.

done that already, to no avail......

i've got an AFM, it's off an R34, but its the exact same as the S1/2 Stagea, S2 R33, and R34.

(it was used on a S1 stagea to diagnose a problem, so i definately works)

$125 and its yours.

cheers mate, ill let you know via PM

cheers everyone for your help, greatly appreciated...

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
