I'll let the gearheads tackle your OBD 1.5 questions. I think GM should have waited for 2.0. Think of yourself as a Vista OS owner waiting/hoping Windows 7 is gonna make things all better.
Purgatory is nowhere near or like Pittsburgh ROFL! It's a Hamlet with no official name. It has 260 residents. It is situated in Susquehanna County within the Township of Silver Lake. It is the most sparsely populated county of PA in the NorthEast section of the state. We dont even have mail service. We pick our mail up at a Post Office designated Brackney, PA. The town disapeared almost 100 years ago with the oaks and maples that were clear cut. But a bar and a Post Office remain to serve several Hamlets in the area to small for one. We have no Police, no street lights, no mail delivery, no trash pickup, and in the winter rely on County plows to dig us out when they feel like getting to us. I heat with wood and have backup electric thats used often. To us, Possum is the "other white meat". Here's a pic of ny driveway.
