Default New Engine or New Cats

I need some serious help. i was driving my 06 maxi one day everything seemed fine. just checked all the fluids before i took off. i stopped to pay toll and when i stepped on the gas the rpms wouldnt go over 2000 ...when i pulled to the side ..the car was putting like it wasnt get oxygen or fuel. Nissan supposedly changed A cataly converter. but there is 3 so the one coming directly from the motor looks rusted as hell along with the 2 small cats .when i brought it to my mechanic he changed the coils, starter, n negative battery cable ...but car still doesnt run properly ...he tells me now i need a new engine . when the car starts it sounds fine for a lil while but when u drive it the engine starts knockin n the rpms wont go over 2000. i believe i need a cat or exhaust sys????
HELP

calm down ,

First do you have any SES (CEL ) engine light on/codes?

you need to start from there, if you could take a 5-10min video of your car being started up and idling,

if Nissan replace your cats , #1 you should have went back for a follow up, if it had something to do with the cats, they are responable.

Im not sure why your mechanic started changing all that unless there was a code.

what year is your car, mileage ?
