Engine Cutting Out?

Hey I had/have (not sure if it's still happening b/c I learned to drive in such a way it didn't happen) this problem with I bought my 33GTS-T

Basically if you just start getting on boost (>3200rpm or something) then put the clutch in the rev counter will fall all the way to 0 and your engine will die, is this right?

Two things you can do to to avoid the stalls:

- When you think your driving might cause this to happen, blip the throttle after you go into neutral/put the clutch in, and it'll stop the engine from dying

- If it does die and you're still rolling (even a little) just drop the clutch whilst in second gear and it'll force the engine to turn over and spring back to life.

Very annoying problem when I first got the car. A year later and it doesn't seem to happen anymore, but I'm not sure if that's because I just adjusted my driving to avoid it or in the 3x services between then they fixed it unknowingly.

nah exactly like how i said it.

put the foot down every now and again usually its alright but sometimes wen i putt my foot down for a few seconds then hold the clutch for a bit its just dies.. reves drop from where ever its at at the time then drops to 0 and dies.

it happened once wen the engine was cold so i warm it up before i drive it but sitll does the same thing even wen i been driving for half an hour or so.

any ideas mate?

yup ive got a bov that isnt plumed into the air box or anything jsut straight into the atmosphere ..

what can i do to fix that? jut plumb it into the air box or wot?

The main issue is that the AFM is getting an incorrect signal due to the registered intake charge blowing off.

You need to use either a hybrid BOV which vents both to the atmo and recirculates (which still isn't a 100% fix) or replace the stock bypass valve and return the charge to the system after the AFM so it doesn't overfuel.

Yeah basically it is overfueling because the ECU is reading* air that isn't there.

On a side note, wtf are you clutching in around a corner? you should always go around corners in gear with clutch out.

This has just started happening on my car last night.

However the IDLE of my car is extremely rough. At idle, my car is missfiring that badly, it sounds like a 350 with the lumpiest possible cam it in. Yet while driving at anything above 1750RPM, it wont miss a beat.

Any ideas? I have read that it may be worth cleaning the AAC valve, however i do not believe that it is the coil packs or plugs, as if they were not funcitoning correctly, my car would missfire throughout the entire revrange. At idle, there is more resistance than while revving....

I have no idea why it wont idle properly/missfires like a b!tch....

Well it has been missfiring on idle for a few days last night, so i'm more concernced about that.

I have checked that, and all vacuum hoes are connected.....any other ideas lol?

Could it be my stock AFM is screwed?

New spark plugs went in about 1500-2000kms ago, copper plugs. Have always used NGK copper plugs (cant remember the code for the plug) and have never had any trouble.

AAC valve? Coil packs? Piston rings? I dont know what it could be >.<

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      M35 VQ25DET starter motor

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
