That was my thoughts as well. When the MAF code popped and the guy immediately went to "change the MAF" without any kind of troubleshooting I was very skeptical.
To me the rattle is a more pressing issue than the fault code.
If the cat is plugged and I pulled the upstream O2 sensor out, would that let that side of the engine breath enough to limp it home 60 miles?
I live in CA so a bad cat is the absolute last thing I wanted to hear out of a vehicle I just got since CA cats are ridiculously expensive and you can't buy a used one from pick n pull or someplace like that.
