    Yes, sort of. The bucking and stalling was due to the ECU nulling the upstream o2 because the readings were so far out of what is expected. It was basically running permanent open loop. The reason is that the subaru 440cc injectors are rated at that flow at a much higher rail pressure than the sx4 is rated at. Those injectors in the sx4's system are somewhere around 360ccs IIRC. So my base fuel map was overly rich and it was not able to compensate. I have since swapped to the stock injectors to try to get rid of my downstream o2 codes. I still have not figured out the solution to that, and now since I am a father of 2 I don't have much time to mess with it. I actually will be posting the car for sale soon as my current lifestyle requires me to have a larger car that can fit a tandem stroller.
