Wastegates spend most of their lives closed. On occasion, when needed, they are opened. So I'm trying to figure out why it would get stuck in the open position....as mine is on my 91.

Also, assuming the actuator itself is fine, is it usually sufficient to spray PB Blaster on, let sit, move back and forth, rinse and repeat?
