Hello and welcome to Justanswer!
The throttle percent being higher than zero could potentially be an issue but I wouldn't initially be concerned with engine load being 100% without the engine running. With the engine off the MAP signal will be showing ambient pressure which is the same as what it would show with the engine running and throttle wide open.
Are any fault codes setting?
Does load look correct while running; does MAP vacuum agree with a hand held gauge?
