hey mate i had a similar problem and it maybe ether of there 2 things the crank angle sensor (cas). if you have a mate with the same car or some one that you could lend it off just to try it. just mark it swap them and try it. or you can clean your aac valve but this usually only will conk you out when you go down to idle. if it is all carboned up when you let go of the accelerator it will just die on you.

well it is a bit confusing sorry about that but i hope this can help you out cheers

yer that is what happens.. after boost when i slow down to say a speed hump

at idle it just dies on me.. 1-2min later it will start up.. i think ill try that it sounds like that could b it..! cheers mate.

If no luck on the AAC, clean the AFM.

yer i cleaned aac out.. cleand afm.. replaced fuel filter too.. stalled on me today while driving at 60km...? what the hell.. 2min later starts up fine.. if its not bov.. maybe fuel pump.? dont enjoying stalling at major intersections much..!

Im guessing the bov is venting to atmosphere? looks like thats the problem if it is.

yer it is.. might move it an see how it gos.. if it still happens im going to go nuts.. not loving stalling every time i drive !

Another issue I came across once that was similar to this was that there was a loose wire on the ECU harness.

Just to cover all bases, remove the kick panel, start the car and GENTLY wriggle the ECU harness and see if the car cuts out.

sweet ill give it a go..

sweet ill give it a go..

man..! started the car up an let it idle for 2-3min an it just died an stalled.. starting to think its the fuel pump.. had to get it towed.. just kept getting worse an worse.. then it woulnt even start to drive onto the toetruck..!!!!!!!!!! hoping its the fuel pump..! strange but.! :)

Symptoms point to the pump as a possibility, very common for the old R32 pumps to die, since it's a early 33 the stock pump might be nearly 15 years old now

yer.. hoping soo ill keep yous informed.. hope to get it back monday or tuesday after the boys down the shop do all the tests an stuff on everythig..

well turns out it was the fuel pump..! so its all good now.. sweeeeet.. :down:

HOLY CRAP!!! I thought i was the only tard to stop at a major intersection, holding up Melbourne's traffic. Great FUN! So the fuel pump solved your problem. I'm gonna get one on Wednesday see how I go.

P.S I feel your pain!

    • After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive 
    • Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.
    • I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.
    • No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.
    • Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
