Throwing parts at a code on it's description alone isn't the way to do it. Subaru doesn't use an igf circuit like Toyota typically use, so ignition coil performance has to be modelled from other factors. The ecm may be monitoring the waveform on the trigger circuit, or it may be a completely indirect monitor based on other factors. Without knowing that, you effectively know nothing about the codes.
