I stopped reading this thread when I decided to go and check the grounds in my Forester. I am still trying to find all of them, but I am also going to have my starter tested today. I really want to pay someone to finish the small things. I could sell it as-is, but it could be something like your grounds, a small fix that makes a big difference, and someone else benefits from my loss. Mostly, I just wish that I knew why I am still burping it after two weeks.
Edit! I cleaned some more grounds and it starts easier now! I also found my coolant temperature sensor, connected it, and the gauge finally works properly, so who cares if it may have air!
