The fuel pressure is the same as when it started fine. The tune hasn't changed. We messed with it to see if we could clear it up and ran it down pretty lean. We adjusted on the IAC motor to see if we could catch it before it stalled. Like I said , it's hard to imagine all the injectors leaking but that is the next step I guess. The fuel filter looks good so I can't see trash being a problem

what does scanner pro report at Key on Engine Off. Look at the dash then check the item list? What's the reported BPW, IAC Position,, TPS voltage and percentage, (MAP) = KPA and KPA Raw, KPA Voltage. Compare your logs from when it ran great to when it started acting up.
