Partial plugged cat or something else

I unplugged the maf and that changed nothing. Unplugged each injector individually, the engine stumbled when disconnected so they're all working. I temped all cylinders 2,4,6,8 I couldn't get a reading on as the machine only goes to 320. On 1,4,7 3-320 but on 3 it barely hit 200. In drive, I foot braked it and floored it and it barely makes it past 2000rpms.

You have the 212/218 right? You should have at least 18" vacuum at idle.
Plent of times I've seen vacuum leaks at the lower part of the intake gaskets, where it's very difficult to spray parts cleaner. ESP if you still have the foam baffles under your intake. Sometimes only a smoke machine will show the vacuum leak.
How old are your intake gaskets, and how many times have they been reused? Are they green or red?
