Okay, I just got mine out, it was in fact a dual stage. The big side was stuck wide open. I managed to get it back closed, and boiled it in water, and both sides opened and closed fine. I dont think Ill risk putting it back in though. Ill just hold on to it. Rockauto has the dual stage motorcraft for festivas but I dont know if its the same. Ill just stick my standard replacement in.
