My 94 Yukon has that older vehicle exhaust smell. What should I be looking to change or adjust?

What exactly does that mean? Is your check engine light coming on? Is it smoking at all? If so, what color? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

No smoke or check engine light. but as far as tuning, the only thing i have not done is plugs and wires. Or for that matter check my engine timing. But to best describe it smells "Not Clean" like its not burning up everything it should be efficiantly. Does that help? Some smog device? If so which one's or how can I determine? Thanks

No, I'm afraid "not clean" is not a diagnostic term and doesn't identify anything. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
