Mate, you're gonna need to give us alot more information that "the engine cuts out".

How often do you put your foot down ??

[Psyrus]

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.

yeah exactly my problem ae.. to the tee i got a 32 tho

umm yeah thats what ive been doing hey just dropping the clutch but i wanna try fix the problem..

i find it happens wen the engine is a bit cold so i warm it up befor i drive it but then sometimes just randomly wen i clutch it round a corning it will just die and the steering goes all hard so i just drop the clutch

not a clue wot could be causing it tho??

If you have an atmo venting BOV with an ECU running an AFM, this will occur.

CHECK for an atmo BOV!!!

[57ept]

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.

haha tru.

the mrs lives on a corner so sometimes i clutch it thats the only time it really cuts out, and wen i cum to a speed bump and i leave it in first and clutch it over sometimes it dies but ill try wot the otha fulla suggested

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....

[bubba]

Check all the vaccum hoses going to the plenum, if it's just happened all of a sudden then it's probably a vaccum leak.

[syfon]

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?

[bubba]

When did you last put new spark plugs in? and what sort?

Could try cleaning the AFM but I doubt that's it.

[syfon]

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 >.<

[SKYRYAN]

Get some Splitfires you bum

[bubba]

How bad is it missing? to the point where it's almost stalling? or is it just a regular miss every couple of seconds?

[syfon]

A bit of both mate. It is missing badly on idle and sometimes it completely stalls.

[bubba]

Does it miss under load at all?

[syfon]

No, not while soft/hard accelaration....no missfire there at all, only at idle...
