Update...
Took the bird through AirCare and told them that I don't believe the Canadian cars ever had Cats, although the label under the hood says mine did. After some calls the manager told me that they started installing them on 1985 and newer model Eagles. Bummer... automatic fail. Took the test anyway to see where she stands and get three months insurance. She did poorly, only passing on one or two of the tests. They did however run it as a car and not a light truck as it is officially classified.
When I was camping a couple weeks ago I must have busted the exhaust hangers and she came out of the bush much louder than she went in to it. A couple of days later the whole pipe was dangling near the ground which I quickly remedied with some wire coat hangers. I had the exhaust all fixed up yesterday and had them slap in a new Cat.
So now I'm thinking good tune up, plugs and wires, etc... go through AirCare, this time make sure they run only the light truck tests, and with any luck...
