1998 2.8 30v a4q cat help

Ok...so I am pretty sure I have a bad cat. however i cant pass emissions without getting a temp fix until i can afford the 1000$ to get it replaced.

currently i just stuck a doubled up spark plug non fouler in 1 of the o2 sensor's the passenger side one, it did not remove the cel(after taking off battery for 40 seconds to check.)

code its running is P0422 - Main Catalyst Efficiency Below Threshold (Bank 1)

does anybody have any idea what i can do for a cheap simple fix just to pass emissions till i can get it fixed. I cant afford to not have a plated car right now(JUST got car)...no car=no job=no fixed cat, plus other problems.

any and all ideas just to get that CEL off so i can pass emissions would be greatly appreciated...cheaper the better.

and no getting a universal cat is not the answer, if i had the 200$ to get that done and welded id have the 200 more to just get the waiver. my job requires me to drive so no driving=no money =/

well, disconnecting the battery wont clear the code or turn off the engine light. You need an OBD2 scanner
