Greetings fellow subaru lovers, I apologize if my first post on your forum is a simple question, but I need advice badly. My '01 RS recently started stuttering on takeoff, but only at low RPMs. Actually it happens in any gear below 2000 RPM when I mash the throttle. Steve Barsotti suggested that it may be an air fuel ratio sensor gone bad, which seems plausible enough to me, but I'm having trouble finding the replacement part. ANY info would be greatly appreciated. TIA.
