1994 bonneville no acceleration

just like the title says i just bought the car from some old guy telling me that it didnt have any acceleration. He said it was b/c the catalytic converter was clogged. i get it home and from what he told me i i just cut the cat off ran it straight figured it would have accerleration. still doesnt have any just noise as hell. anyone have any input of what i should look for or check?? any help would be appreciated thanks

after closer examination i found that an animal had lived under the hood and decided to eat the fuel injectors wires to 2 of them. after reconnecting the car is running alot better. i also installed new spark plugs and wires. from a dead stop the car fells like its gonna stall for about a second or 2 the accelerates it also doesnt have wot. b.c the car was running without 2 cylinders and the original spark plugs is there a chance that the cat could be clogged?? restricting the acceleration?
