Car Stalls But Stable Revs?

hi all, lately my car has stalled a few times and sometimes, while driving, shut off then come back on..

i had a prob similar to this a while ago and diagnosed it as afm, i fixed it up as the pins came off solder. but last time when it was afm the idle would go crazy and stall all the time.

this time it doesnt, it will shut off or stall maybe once a trip and the idle would sit perfectly on around 650-750..

any suggestions?? does an old fuel filter cause any of this??

cheers

sounds like afm is gawn

mine would do exactly the same

some days perfect, other days felt like violent misfire

if you got a powerfc, graph your afm signal and see if it drops to 0 volts

      Is it alright to top up with just another green coolant?

      thanks GTSboy. My confusion at the moment is i am trying to locate the ignition, ECU battery power and the ECU negative The closest thing i can find is the for the S15 on Page 8 of the Wiring Specialties web page https://drive.google.com/file/d/0B9F33_M_GgENQnZ6STMxVmVNd1E/view?resourcekey=0-eZ4nNRwRoqa1qvKlWWHm8A I cannot find the same diagram for the R33 RB25DET Series 2 dash plug pin out.... Do you know what the Pins? or know where i can find the same pinout diagram for the RB dash plug? Thanks for the advice on the box... i like a 6 speed so might be on the lookout or the box now.. a topic of discussion for another post...

      Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.

      Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.
