I have same vehicle, and I am going though the exact same thing right now. I thought maybe I asked the question. That is how exact our problem is.
I have replaced the Air Idle Control Valve. Fixed for 72hrs, Then I replaced the downstream o2 sensor 1 and 2, fixed problem for about 2hrs. I have replaced the PCV valve, didn't change a thing! I have cleaned my throttle body, air flow tank, MAF (mass air flow sensor) with cleaner. Did nothing to resolve the problem?
My Check Engine light has stopped lighting up though, battery light remains on as well as the choppy idle, sputtering, and killing it self.
