I have a 1995 Buick Century with over 230k miles on it, and it failed emissions. The tech said it was giving off too much raw gasoline fumes at lower RPMs.
My first thought was to replace the Catalytic Converter, because the old one was replaced with a straight pipe.
Before replacing it, I wanted to see what else might cause this, to potentially avoid the parts and effort.
None of the spark plugs are fouled but I don't know how to test them other than that.
I would hate to replace the cat just to fail emissions again.
