Thanks to this site, I went out and purchased an OBD2 today from Walmart. It cost me a hundred bucks, but that is equivalent to just three trips to the garage to have the check-engine light checked. On top of that, I found something called PlastX for cleaning the plastic headlights which had gotten foggy and oxidized. Now, I'm going in search of Refinish Restorer to deal with the cladding.

Thank you to everyone who has responded. I feel like I've just walked in the door at a party and everybody knows my name...(Norm!).
