ok thanks! ill try all that! but i dosconnected th coils packs once before seperatly, and none of them changed the the idle speed or made the motor want to run rougher, everything seemed to stay the same. and that makes no sense?? this is so confusing.
i have wraped my dp, i will get a heat shield asap!
also if i do get new coils, do i need them off a nother 2003 wrx? or are ann coils from wrx's to sti's interchangeable?
Thank-you everyone so far!
