2 cats in two months.

I noticed that my car really stuck thrusday. Well Iam heading to school and I notice my check engine light is one. Well last night I went some were and as I got out of my car It stuck worst then before. I remberd that smell from nov when I fried the first cat. Why cant dodge use a high flow cat? If this keeps up it looks like iam going to be getting a new cat every few months. By the way the car has 30,000 miles on it. It also normal every day driving.

I feel sorry for your convertors. Its not thier fault its yours. Cats don't stink or even fail on thier own. Btw, Flow has nothing to do with it. You have for too long, been ignoring the fact that there is something chronically wrong with your car. Failing Cats are just the result of you unable or unwilling or to fix it.

A "fried"cat gets too hot. So where does all the heat come from? Your kick ass, wicked awsome, super powered machine? Hardly..... Its from too much unburned fuel getting to it, usually from an excessively rich A/F.

Your two cats are,,corection were just trying to do thier job, but incompetant tuning(750cc injectors at 58psi, F'ed up SAFC ect) or a failed part(upstream O2, fuel regulator, exhaust leak,ect) is Forcing the cat to try to burn all the extra fuel in the exhaust. As it burn the extra fuel, its temps rise it stinks and if ignored long enough the bricks will melt and plug up the engine.

Sorry if im sounding like your dad, but I really want you to fix the problem and not waste money on another cat. That will only treat the symptom but not cure the cause.

Running leaded race gas will eventually contaminate the cats but probably not in a month or two time frame. Still not something you want to be running all the time. I'd check for fueling issues as suggested.
