  1. P0171 is usually indicative of a vacuum leak.

    Possibly turbo inlet, most likely plenum to TGV O-rings. Do you already have the newest orange gaskets? This is probably the most common problem when I get brought subarus that are not running right. Good luck!

     

    Edit: forgot this was sidefeed, I remember reading your thread awfulwaffle. Good call to check as far as the misfires.

  2. I don't believe the 09 are compatible with the newer system.

     

    You need a tool (I have an Autel TS-508, there are cheaper options available)

     

    ATEQ Quickset has a summer winter switch mode and can program the subaru tpms computer.

  3. What are the High and Low pressures at idle? 3000rpm? It could be a bad output from the HVAC control, you would have to do some testing when it fails. (Manifold gauges hooked up and a meter or probe to check signal to the compressor (or sensors).

     

    Found a diagnostics chart:
