Hi guys, I'm a first timer so go easy on me. Just talked my missus into gettig a 03 wrx and we both can't get the smiles off our face everytime we drive it. What a car! had my first problem today though, the car was running rough as after drivin about 200m after i put in the k&n filter i pulled over and it stalled and would start but immediatly stop. i unplugged the air intake sensor and it was running but not well. does anyone know why this happend and how to fix it?
