A range of things. Need more info regarding your car (mods, any servicing you've had done, what sort of driving condition when the stalling occurs).

Usually it's fuel (pump or injectors), spark (plugs, coilpacks, ignitors, wiring), or tune/ECU related. Can also be [bad] idle control.

I just bought the car a week ago from an importer. Its all stock for the exeption of cat back exhaust and a oil filter relocation kit. I've replaced all the fluids so far but thats it.. and im just waiting for the spark plugs so i can replace them.

Its very likely electrical...

have a close look at the wiring harness.. specifically have a look at things like the part of the loom for the coils... that sits in a very hot area and over the ~20 years its been there, has been subject to allot of heat that will have caused the insulation to degrade.. its not uncommon for intermittent short circuits to occur here.

If you need a replacement for the coil pack look, have a look at wiring specialties in the US.. buy direct... I looked at some cheaper stuff on ebay a while ago that claimed to be made by them, but it was likely a knockoff.

 

When the problem occurs next, pay close attention to what you were doing at the time when it happened. Try to reproduce it by taking the same action (ie, turn right at speed, hit a speedbump at a particular speed, etc) - this might give some insight into what the cause is.

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.

      Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
