2006 Outback Wagon - 250k miles never any engine or electrical issues. Power wash engine compartment after routine oil change. Upon completion backed out of bay; She started then stalled with an "Er HC" Code in a strange place... ABOVE the Odometer. Hasn't been able to start since (6 months). Hooked up Computer; it would not come on. Bought new computer; same thing. My mechanic has gone through ever connection attached to top wire harness and nothing. Ideas????
