OK, if it idles at 1000+ with the AAC, its not an idle airflow problem. The cold start valve just gives extra air when the engine is cold, but you have enough air without it to idle at 1000. I think you are back to a fuel problem, sorry. Can you see the fuel pressure staying constant or does it drop as the revs drop to a stall? -

Well, I was using ECUTalk software if that helps? Not sure if that only can see engine codes? Is there any other software I could give a try? Or any way I can get a blink code? -

I never touched it, it should have. I'll try to give it an adjust. With IACV plugged in, it idles at around 1120RPM on average. Max 1200 RPM, Minimum 1025RPM before it starts dropping right before stalling. Took the data from the Nistune logs. -

Well, yes, every CU on the bus is available via the Consult port, but whether the scanner you are using is capable of talking to the TCU, the ABS/TCS modules, etc etc, is what is at question here. Many of them are only for engine codes. So, if you have one of those, you won't know if the ABS is having a bitch.
