Better yet. Sell it to me. We don't have any type of smog stuff in my county.
Egads...

we're talking about a car with a Catalytic Converter being "rich enough to smell it", and we're thinking a gast-tank additive will get us to pass.....


How about seom real troubleshooting, diagnosis, and repair regarding the over-rich condition that has killed your cat and made you fail the smog?

Just a thought...
