    ICV buzzing with car turned off

    Anyone encountered this before. Its getting power with the ignition switch off, which is a big time drain on the battery. Anything of value welcomed to this thread.

    Possibly a bad main relay. Check for 12V at the injector harness in OFF, then one of the two pins on the evaporative purge valve. If there is voltage at both of these spots, your main relay is stuck shut (30 to 87 always on).
