Hi guys I have a 1989 Buick century. i know this isn't a buick site!!! I need help though. Anyway, It has a 3.3L v6 with fuel injection. The darn thing just won't pass emissions. Here is a list of what I had changed so far.
The symtoms are it smells like rotton eggs and blows out black smoke. I'm failing hydro carbons and carbon dioxoide. Please I need some help!!
I have spent well over $600 buck the car only cost 1200!
