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 :thumbsup:

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.

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/

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

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
