trouble code not making sense??
P0420 (M) 1/1 Catalytic Converter Efficiency Catalyst 1/1 efficiency below required level.
ram 2001 5.9
This code showed up yesterday, I just had the cat replaced (high flow magnaflo).
Could this be one of tha 02 sensor's? If one of the sensors were bad wouldn't it show a different code. Could it be the computer not seeing the OEM cat? Or possibly the something downstream like the muffler causing the problem.

Thanks dhvaughan, I will look into that. Last time i went to the local parts stores, advance, oreily, auto zone, I kept getting different answers on how many and locations of the 02 sensors. They were telling me things like is it the right or left or you only have one and such, they drove me nuts and didn't know who to beleive. So I put it on the back burner. I geuss I'll give it another shot LOL
