Mileage is 122,000, Is my catalytic converter still under emissions warranty?

Hello, you'll need to check with your local Dodge dealership in Indiana to see what the catalytic converter warranty is there. I'd say - probably not covered, as federal emissions warranty limits the coverage to 7 years / 70,000 miles - whichever comes first. Naturally, Indiana may afford you different coverages. Either way, I don't think you have a problem with your catalytic converter. It's an engine performance problem that can be caused by many things -- unlikely to be the catalytic converter. Hands on testing is needed. Even if you take it to your dealership and anticipate warranty coverage, you'll have to OK them to check out the car and maybe it isn't the converter and you're stuck with the bill. www.repairpal.com/repair-shops I'd consider fuel, spark or air intake concern before exhaust flow.
