Well the subie is finally running and NOT stalling What fixed the stalling? Not sure but possibly something in the throttle body. I did a JDM engine swap, long block only. Kept the original intake. Still stalling in hot weather. Put the JDM intake on it with the original injectors and new oem seals, and changed/swapped some other bits that were incompatible (fuel rail, intake harness, coolant crossover pipe temp tensor, passenger side AVLS solenoid assembly, airbox hose to the block next to the pcv, plus longer brake booster vacuum hose to get to the right hand drive fitting on the intake). jeepers, this is why everyone keeps their intake. No stalling. Its been about 3 weeks of driving, city/highway in 88+ degree weather. Unless the mech at subaru changed them, the only two unswapped parts are the throttle body and the EGR. Everything else on the intake was swapped at some point. I'm cautiously optimistic. And maybe the original long block is probably fine as a spare if the rear main seal and head gasket(s) are redone.
