Yeah, I just got back from the vacation.
Parts have been on back-order since I left in June. They should be shipped by this Friday. I ordered all new fuel injector seals and clips, new manifold gaskets, new cylinder head-to-manifold gasket and a new pressure regulator.
My poor car has been sitting with the hood open and half-apart for a week and a half now. I really miss driving it.
If this list of parts doesn't fix it, I don't know what else to do. <crosses fingers>
