Rayg91

thank you ill check that out but i did find a nice pair from a dohc ej25 that i had in my piles of parts

ok what rails do i need?

hey i have a completely stock 91 legacy turbo i think i have a bad injector and am upgrading everything anyways so i bought some wrx blue 440s can i jus put them in or will i run rich?

can anyone tell me what fits from other models and maybe some recommendations thnx

i have a switch on the dash of my legacy that I'm pretty sure locks it into 4wd whats the deal with this?

im plugging the two black connectors together to get codes. I've replaced the main ground from the batt to block and to fender. ill check the ones on the manifold and ill clean those plugs also and see how it goes

This mornings codes are 49(air flow sensor) 45(Atmospheric pressure sensor) 13 (cam angle sensor) 22(Knock sensor) 24(air control valve) 31(Throttle sensor)

iac, maf, knock sensor, cam angle sensor, tps, 02, atmospheric pressure. some have come gone and came back. also air flow sensor

i just bought this car and it has about 6+ random codes ill list if needed but I've replaced alt and batt. I'm convinced its not the sensors at faulty any ideas I'm thinking grounding problem, maf, vacuum, maybe just the knock sensor? thnks
