Default P0420 After Overheat And Repairs

I have a 2006 wiith 170,000 miles.
It overheated and hadto replace the water pump.
During the repair they got the system out time and ended up having to replace the timing chain.
Somewhere during the repairs one cylinder started missing, they swap plugs and then the coil still missing so they determined it was the Engine processor. It was changed and reprogrammed.

I got he car back it ran fine for about 20 miles then I got a P420 code.
had it coded and Autozone says it could be the cat, a large vacuum leak, fuels system fault or ignition sytem fault.

I never had any problems prior to the overheat problem and am not the orginal owner.

so... my question is, would overheating damage a cat? Or
is it possible there may be a vacuum leak?
I just saw a post about the PCV valve and will change that this weekend.

Would an overheat cause a problem to the processor as well?

Has anyone see this happen?

Thanks for any help.
