I have a problem with my 02 Wrx hybrid. It is running really rich on accel. My prosport wideband says 10.0 (lowest the gauge goes) at about 50% throttle. Up to that the car seems a little sluggish and feels like its dragging stuck calipers or something. Anyone have ideas? Tried upstream O2... Nothing changed Thanks Car info: hybrid build, 660 injectors, FP18G turbo, auto tranny, tune by Ron@RS.
