I just had a remanufactured Carb installed on my Caddy today and when I drove it the car felt like it was set too high. Now There is a significant difference in the way it ran before, and the way it runs now and that could be that it's running better with the new part, but for some reason it feels like it's too high. How can I tell if it is indeed too high? Also I was told that my air pump for the emissions which is part of the belt drive is crooked. It leans in towards the middle a little bit and is now running without a belt on it. What would be the reasons that thing would be crooked like that? Thanks.
