first thing im going to do is burn this sh!t Arco gas out of it, and put in some Chevron or Shell which the car has run on all its life... rather odd, that the FIRST time i put Arco in it, the light comes on... from what ive found, Subies have a notorious CEL throwing due to bad/low quality gas... just wanted to know if it was a major problem, or could be a major problem... the motors for these cars aint cheap, it would be wiser to go rip the drivetrain out of an STI and throw that in it instead.. plus it would be 300+ HP of Turbo charged madness...
