Car Keeps Shutting Off While Stopping

[Panko]

Well, if the ECT sensor is faulty, it will confuses the ECU and when my ECT sensor went kaboom, my idling was rough and sometimes shoot

up to 2000 rpm as well but not constantly, most of the time the idling would drop so low and cause the engine to stall.

Do you see any black smoke coming out of your exaust while idling or before the car stall???, Check the spark plugs as well

I will do that

the car is getting checked out tomorrow finally thanks to the good lads at active auto elec in bayswater. Everywhere else was lame. The car has been sitting in my driveway and ive been driving my sisters excel as motivation to hurry up and get my car fixed.

Let me know how you go there, always been meaning to pop in for little jobs as it's near work.

Well it turns out it wasn't the alternator causing the stalling but i did have a problem with my alternator. The belts were worn out and squeeling so it wasn't charging properly. Apparantly the stalling should have something to do with the intake. Perhaps a leak somewhere. As I said the other day I cleaned out my AFM with AFM cleaner and reset the ECU so that won't fix it. The guys there recommended I try out Race Pace which I am sure you guys have heard of. Otherwise I found them friendly, they worked fast and charged a fair price so I would go there again Ilama_au

Might be worth trying to clean your AAC valve mate, just as a last resort. This can fix idle hunting issues.

Someone did a DIY on it : http://www.skylinesaustralia.com/forums/topic/110431-diy-aac-valve-cleaning-idle-reset/

thats if the idle is fluctuating and unstable though, dunno if it would entirely help with stalling though

my old skyline had a fluctuation problem and my mechanic fixed it.. forgot how it was a long time ago. I'll have it checked out asap

last night we played around with the pcv valve, checked for leaks and then adjusted the idle speed. It was sitting pretty low before (550rpm) now it is sitting at 650rpm and there are no more issues? I still want to find out what was causing it
