I am going to do my emission here soon,(because I am a moron and forgot to get my car registered earlier), but that I am going to fail because the person that I bought the car from had put a new cat-converter on that I would imagaine either doesn't match my Acura model or is just to low grade for the CPU to recognize.

When I dealt with this last year the mechanics said it was an o2 sensor that was out, but I think they were just jacking me. They put the new o2 sensor in and the CAT working below average efficency.

Does anyone know if there is an easy/cheap fix for this. I have heard that Acura cats are like 600+ and god knows I don't want to drop that wad of cash if I can get a good aftermarket one for hella cheaper. But I do understand if you get what you pay for.

Thanks for the time.
