swapped my old EJ25D back into my black 98' outback "outblack" meow I have ALL the codes
P0463 (circuit)
P0463
P0183 (circuit)
P0183
P0446
P0141
It is almost impossible to get it started it will tick over at 100-200 rpm for a few seconds and then fire up to normal idle (800) not warm-up idle (1500) and if I give it any throttle it boggs down until its "warm" then it will shudder and stutter like the knock sensor is bad (but it isn't) till 1500-3500rpm depending on how she feels (typical subaru humanity showing through) then if fires off like a 1980's turbo SAAB. changed the fuel pump/sending unit so that's not it, pulled off the plastic cover from the filler neck and that was all good still, it doesn't have a charcoal canister box thingy behind the pass side rear but i bought it that way and it worked just fine. doing some research those codes come up often in engine swap situations, anyone have this issue? cheers!
