2002 wrx with mods has misfire across the board
i have a 2002 wrx with crower 264 cams, ferrea endurance spring kit, brian crower vavles, a perrin bov, and short ram intake, accessport v1, cobb uppipe, borla shorty down pipe, ( still have 3rd cat) and an hks hi-power exhaust. i have misfires across the board.
the misfire is very very very slight. i also have a what i think is low idle ( about 500 rpm) the light doesn't flash usually comes on at idle and stays on solid ( not like a normal misfire) and when it comes on it's all for codes at once not just one.
i was wondering if anyone else has the same or similar set up or has herd of this problem and has a solution
any questions feel free to ask. thank you
