Catalytic converter out of spec
The check engine light on my 18-year-old Dodge Ram was coming on every few months for an out of spec catalytic converter. I used Rislone Cat Complete per the instructions and have not had a problem since. Replacing the catalytic converter would have cost around $2000. Great product. I now use it as a maintenance routine once a year. Truck runs good. No more check engine light.Verified purchase: YesCondition: New
