This doesn't happen all the time but has happened 6 times in the last 2 months. 3 times in 5min.

But ill just be driving listening to music and the car will just turn off, hold the clutch in and turn her back on she is fine, but i would prefer to stop this b4 i get hurt. Not sure what it has to do with, was thinking maybe immobiliser.

Just wondering if this has happened to other skylines and wat can be done to fix it. My mate says it has happened to him once.

does the car stall after dropping too quickly from high revs??

my r33 s2 1997 used to do this because the aac valve would not pick the revs up quick enuff to stop it from stalling.

if this is the case, try cleaning the aac valve at back of the intake manifold. bronze coloured solenoid.

sounds like thats the problem. or something similar, if it gets driven a little hard or high rev it occasionally dies. It happened on the bridge today, so i don't want to even imagine the worst place it could happen. Do you have a picture, or describe where it is, when it comes to turbo engines i don't really know my way around them.

Problem has come back again after driving it a little hard the car tends to shut itself down while driving, did it at 100km/h friday night.

Got the computer read this morning and there is no recorded problems in the computer...

The controls said it was running lean at idle, then rich when accelerated.

The part under Hicas said there is an abnormal rev (problem 25 on the machine)

Thinking might have something to do with the fuel pump or fuel relay or something. Where about is the pump located and do ppl change these from the standard pump to r34 or something?

When the AAC valve was clean it didn't shut off after that, but im guessing its full of carbon again, so what would be the cause of excess carbon being produced inside the aac valve?

the fuel pump is in the boot of a 33 next to the battery, you gotta take out the back trim in the boot to get to it. most of the time they get changed to bosch/walbro/nismo fuel pumps any one of these.

can the aac valve become full of carbon after about 4 months...would have thought it would take longer than that.

Well i wouldn't have thought so, gonna pull it off later and have a look, if it is then something is creating it quicker than it should.

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      What about if you just give it direct 12v and earth?
