hi everyone. im having a little trouble with my 02 wrx. it seems when the radiator fans come on they make the engine shutter. i thought nothing of it until they made the car stall. the car only shutters when the fans come on if its in park or im sitting at a stop light. what i dont understand is that if im in park and leave the hood open the engine doesnt shutter as much. can anyone give me a idea of what could be wrong? or is this normal behavior for a wrx. i dont know what would be considered normal behavior since this is my first turbo.
