ok heres the story,

i have a mildly modified r33 s2 gtst, i have a after market ecu that still runs the stock afm, a few days ago i replaced my metal mesh pod filter which was quite large to a signifacntly smaller apexi one, i think this may have something to do with it.

when i drove to work yesterday morning (5am) the car was fine, but on the way home about 4pm the car was sputtering abit and eventually stalled, luckily outside my house, i drove the car later that night for a short period and it was ok again.

the same thing happened today except i didnt make home, i was able to restart the car after i let it cool for a minute but only for a few seconds, and then the problem repeats itself, heat seems to be a factor here but thats about all i can come up with at the moment.

i will replace the old pod filter asap but that may not be possible for a few days

any suggestions ???

pod filter will not cause this, unless its clogged to buggery, The issue may be however the AFM, somehow during your swapping for filters you might have damaged the AFM possible or got some dirt on the hot wire element, Try spraying this with carby cleaner or brake cleaner.

SOunds like CAS, they tend to play up when hot. Check the AFM is plugged in properly, could be ramdom fuel pump failure, what computer is it?

the computer is a hks f-con s, i had a nismo fuel pump put in about 10,000 km ago, excuse my lack of knowledge but what is CAS. it is possible i have damaged the afm but why does it work sometimes and not others?

I could almost bet it is your plugs playing up.......

My nephews car would just stop....he would have to wait until it cooled down

then drive it back home...lol

I replaced his plugs...and presto....no more stops.

Replace your plugs.

    • What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.
    • Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan. 
    • The BES920 is like the Toyota Camrys of coffee machines. E61 group head is cool, however the time requirements for home use makes it less desirable. The Toyota Camry coffee machine runs twin boilers and also PID temp control, some say it produces coffees as good as an E61 group head machine.
    • And yes with a full tank it will hit limiter free revving or driving 6B6CDF6E-4094-426D-A9CB-6C553475FE36.mp4
    • One way of putting the fuel surge idea to rest, is that even when in neutral/clutch in or free revving it still has the same issue, it can’t even get to limiter (7800) so to me that says it can’t be g force, I’m not trying to argue I just want to find the f&$king issue 😡
