Hey all.

I've been trying to solve an intermittent misfire recently and I think its down to being either the afm or ignitor unit. Before everyone jumps in and says "gap your plugs", I should mention that it only misfires/stutters at light or trailing throttle between 2-3k rpm. Very wierd.

Before going to one of the bigger workshops and wasting their time, I thought I'd try to diagnose it myself. So does anyone living south of the river want to lend me a hand for an hour or so? I'd only need to salvage those 2 parts from your engine bay and test drive with them for a few minutes.

Gradenko, ive had similar issues with my car and it was also AFM, id almost say for certain thats it. I even took my car to a workshop and had them test it all via the diagnostic port, even changed the plugs thinking it was that, cost me $80 and it still didnt fix it. Diagnostics said AFM readings were within spec.

In the end i resorted to a backyard fix thinking it was the AFM, ignoring nissans diagnostics. Sure enough a drowning in contact cleaner and it was running perfectly again.

Gradenko - I'll be fitting my replacement turbo tomorrow morning so the car is already in bits. You're more than welcome to come round then and borrow the AFM for a while... PM me if you're interested...

Dsturbd, I'll take you up on your offer. Next weekend perhaps. I'll pm soon.

Went to Garage Malaga today to swap bits with cam. Found out that series 2 afm's are very different from series 1 afm's, so not much testing was done. Did clean the afm with contact cleaner though, but that made no difference (thanks anyway, red17).

    • 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 😂
    • 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
