1995 Saturn SC2 Question: Catalytic Converter problems?
I resently had my catalytic converter replaced and now thesame problems i had before are 10x worse...i have this rattling sound everytime i turn right i sounds very loud and now my engine light comes on quite frequently and that never happened before..so would it be my catalytic converter or a bigger problem? - troubled2009
